Let's meet and talk books
Hi everyone! Let's gather and share our reading.
As usual, we will meet at the fourth floor of the Central Library as it has good facilities for book clubs and it is also free to use. No extra cafe money to spend.
Idea is to meet and connect over books. Each participant present 1-2 books they would like to recommend or just talk about, and then we'll see where conversation leads us. Again, there is no limitation to genre or type of book you are reading. The point is that we are free to read whatever we want and then share those reading experiences, so remember to be respectful to each other.
I hope to see as many of you as possible. :)
Café Philo Copenhagen
We meet on Saturdays late mornings to have a casual, meaningful conversation on topics of interest to everyone chosen on the spot by majority voting. So please feel free to propose your own topic!
Everyone is welcome to talk, but if you prefer to just join and listen, that is perfect too.
As the contacted cafés usually only give reservations to eating guests, it is very welcome if you order something to eat during our stay. This is however not mandatory.
This event is in English.
The exact place can still change.
Fun social extraordinary Saturday run
Join us for a trail run/jog/walk!
We are not a typical running club, so please read about the concept in “about us”.
How it works: we don’t know in advance where the trail will go, but we know it will be fun! A member of the club, the 'hare', sets a trail, usually marked with flour. The rest of us, the 'pack', follows the hare's 'scent', i.e., the marks. There will be a 8-10 km trail for runners with shortcuts down to 5-6 km for walkers and those who need a slower pace. We have no set pace - run/walk as slow or as fast as you'd like. After the run we enjoy some refreshments and socialize.
Come a few minutes before the start so that you can say hi and leave your bag in a designated bag car before we set off at 14:30.
Don’t worry if there are few registrations on Meetup. We have existed for 44 years, and a lot of our members (anywhere from 20 to 50 people) just show up.
Four-legged friends are welcome!
We never cancel.
See you there!
Shut Up & Write!™ Copenhagen
Join us for an hour of writing! We’ve discovered that it’s strikingly helpful to write with other writers. See if it’s true for you at our Copenhagen Shut Up & Write! sessions.
Be it a book, blog, script, essay, dissertation, résumé, melody, poem, or just plain work stuff, you are invited to write it with us. No one will see what you've written or give you unsolicited advice. Instead of just thinking about writing, come and get some real writing done.
SCHEDULE:
- 15 minutes of hellos and getting settled; maybe some quick intros.
- Then, the timer starts! : writing for 1 hour.
- After the hour is up... chat / take off / keep writing, if you're on a roll.
OPTIONAL SOCIALIZING happens once the hour of writing is complete. Writing can be very solitary... connecting (and sometimes even commiserating) with other writers is a cool thing.
It's best to be on time, but BEING LATE IS ALSO OKAY: just show up and get settled, then check in with us after the session. (We’ll be the ones with the small Shut Up & Write! sign.) If you were on time, please be willing to make room for the friendly latecomer.
What Should I Bring?
Whatever you need to be able to write!
Bring earbuds/earplugs if you want to block the cafe’s overhead music or the occasional conversation by other patrons.

Green Paddling 🚣🏻♀️ May edition
....aaaaand we are back in the water also this year!!!
Kayaking around the city channels is one of the most enjoyable activities in Copenhagen on a sunny day.
GreenKayak, a NGO dedicated to raise awareness to ocean pollution, makes few (open) kayaks available across the city to paddle and help collecting waste floating in the water.
Open kayaks are typically easier to manovre than other types, and do not require EPP2/EPP3 patents.
I booked 2 double kayaks for 4 ppl in total.
It is possible to use the facilities at Kayak Republic free of charge: restrooms, lockers and showers.
**REQUIREMENT**
\- Safety first \- Need to be able to swim comfortably
\- Waterproof gear preferable
\- Sun lotion and sunglasses
\- Change of clothes in case yours get a bit wet during paddling
\- Towel\, if you want to shower or just in case
**COST**
Unfortunately, due to the frequent last minute cancellation last summer, it was challenging backfilling participants with short or no notice, and it was very disrespectful to the group and GreenKayak NGO.
**To reserve your spot, please transfer 150 kr. to my mobilepay 25717293**. The amount will be returned to you if you show up on time, or the event is cancelled for other reasons; **this remains a free non-profit event**.
The kayak rental is free of charge provided that:
\- we are able to pick\-up some waste during our paddling activity
\- we share our experience on the So\.Me \#GreenKayak
**AGENDA**
11:50- Meet up - please be on time 🙂
11:50-12:00 Briefing and getting ready
12-00-13:45 Paddling around Copenhagen channels and return to the start point
13:45-14:00 Return the equipment to Kayak Republic
**DISCOMFORT LEVEL** \- 3/5

Franklin Park Conservatory / Columbus Brewing Company
**History**
The [Franklin Park Conservatory](https://www.fpconservatory.org/)’s roots trace back to 1852 when the Franklin County Agricultural Society purchased 88 acres of land to host the Ohio State Fair. After the fair moved to its permanent home, the city of Columbus transformed the grounds into Franklin Park in 1884. This transition shifted the space from a temporary event site to a dedicated public green space for the growing community. The park became a central hub for outdoor recreation and early civic gatherings in the neighborhood.
In 1895, the landmark Victorian-style Palm House opened its doors, drawing heavy inspiration from the Glass Palace of the 1893 World’s Columbian Exposition in Chicago. This iron and glass structure became an immediate icon, housing exotic plants that residents would otherwise never see in the Midwest. It remains the oldest part of the facility and serves as a primary link to the conservatory’s 19th-century origins. For decades, it stood as a singular testament to grand horticultural architecture in Central Ohio.
A major turning point arrived in 1992 when Columbus hosted AmeriFlora '92, an international horticultural exhibition. This massive event prompted a $16 million renovation and expansion, adding significantly more greenhouse space and the Dorothy M. Davis Showhouse. The festival put the conservatory on the international map and fundamentally changed its scale and ambition. Following the event, the facility transitioned from a city-run park to a private, non-profit organization.
In 2003, the conservatory’s identity was further defined through a long-term partnership with world-renowned glass artist Dale Chihuly. After a successful exhibition, the Friends of the Conservatory purchased most of the glass installations, creating the largest permanent collection of Chihuly’s work in a botanical setting. These vibrant glass sculptures are now woven throughout the biomes, blending art with nature. This addition helped cement the conservatory as a premier cultural destination rather than just a botanical garden.
Recent years have seen the site expand beyond the glass walls to emphasize community engagement and outdoor education. The 2018 opening of the Scotts Miracle-Gro Foundation Children’s Garden added two acres of interactive landscape designed for hands-on learning. The Scotts Miracle-Gro Company Community Garden Campus also provides local residents with space to grow their own food and learn sustainable practices. Today, the conservatory balances its historic Victorian charm with modern commitments to local ecology and the Columbus community.
**Maps of the Conservatory**
Here is the [main map](https://www.fpconservatory.org/wp-content/uploads/2025/08/franklin-park-zones-scaled.jpg) of the Conservatory grounds. Here's a [map of the areas](https://www.fpconservatory.org/wp-content/uploads/2026/02/ConstructionMap-2026.jpg) in which the Conservatory has ongoing construction (see below).
**Summary**
For this event, we'll explore Columbus's highly-rated and very popular Conservatory. As mentioned above, the Conservatory is doing renovations on parts of the facility. These renovations are scheduled to be ongoing until the Fall of next year.
Basically, no matter when you go to the Conservatory over the next 18 months, you're going to see some metaphorical orange barrels. So let's just go now.
**Tickets and pricing**
On the first Sunday of every month, the Conservatory is free for residents of Franklin County and the city of Columbus. You must bring an ID to receive this discount. (Yes, they do check.) Otherwise, tickets are $25.20.
Members of the Columbus Zoo (of which I am one) do get a discount on tickets, though I have never actually bought a ticket to the Conservatory (I've always gone on free days). I believe the discount is $4.
Parking is always free.
If you have additional questions about pricing or whether and for what you qualify, you can reach the Conservatory at 614-715-8000.
**Where we'll meet**
We will meet just outside the main entrance. I guarantee there's going to be a line. The Conservatory is always popular on free days, and especially in nice weather.
**Your GPS is stupid!**
Be careful simply typing "Franklin Park Conservatory" in your GPS and going where it tells you.
The only way to access the parking lot to the Conservatory is off of Broad Street. Unfortunately, since Google Maps is unable to find its way out of a wet paper bag, it has a tendency to want to take people to a mythical, non-existent Conservatory entrance on Nelson Road.
If your GPS does this, just drive to the north side of the Conservatory along Broad Street. Your GPS should then redirect you to the main Conservatory entrance. If your GPS doesn't, then throw your phone away\* and look for the big Conservatory sign on the south side of Broad Street between Nelson Road and Franklin Park West.
You also should be able to use the map pin I've provided, below, and it should properly direct you to where you need to drive.
\* Don't really do this.
**After the event**
After stopping to smell the roses, for those that are interested, we'll head to the nearby [Columbus Brewing Company Beer Hall](https://columbusbrewing.com/location/beer-hall/) for [drinks](https://columbusbrewing.com/location/beer-hall/#draft-list) and [lunch](https://columbusbrewing.com/location/beer-hall/#food-menu).
The Beer Hall's actual address is [200 Kelton Ave, Columbus, OH 43205](https://www.google.com/maps/place/200+Kelton+Ave,+Columbus,+OH+43205/data=!4m2!3m1!1s0x883889a94ac4acad:0xadb2e60240dbc38b?sa=X&ved=1t:242&ictx=111) (it's literally just on the south side of the Conservatory). Be sure this is where your GPS is taking you when you use it, as the Brewing Company has a taproom on Harrison Avenue that is *not* what you want for this event.
We should be at the Beer Hall by 1 if you can't make the Conservatory and just want to join us for drinks.

In PRANIC HEALING® Level 1, you learn the basics of working with your energy aura, including learning to "scan," or feel the energy, to "sweep," or clean away congested energy, and to "energize," or supplement areas in your aura that have a pranic deficiency.
PRANIC HEALING® has been taught to doctors, nurses, massage
therapists, acupuncturists, chiropractors, shiatsu practitioners, and many others in the healing field. It has allowed them to heal confidently and consistently in the shortest learning time possible. These professionals find PRANIC HEALING® very effective and easy to apply.
Other topics covered in PRANIC HEALING® Level 1:
Energetic anatomy: You will learn to work with the network of chakras, meridians and auras to accelerate the healing processes of your body.
Preventive healing: You will learn to remove the negative energetic patterns of a disease to prevent it from fully manifesting as a physical ailment.
Self-Pranic healing: You will learn to apply these healing techniques to accelerate your own healing.
