Early-bird coffee and conversation at [Paris Baguette](https://parisbaguette.com/locations/oh/columbus/3969-merchants-row/)!

**Summary** For this event, we will do the [Rhino Barn Tour](https://www.thewilds.org/rhino-barn-tour) at [The Wilds](https://www.thewilds.org/), a ten-thousand acre conservation center in Muskingum County. It is the largest such center in North America and one of the largest in the entire world. During this tour, we'll visit The Wilds' rhino herd in their state-of-the-art heated barns and learn how The Wilds' animal management team takes care of one of the largest herds of rhinos outside of Africa and Asia. **The date and time of this tour** We will be doing the 1:00 p.m. [Rhino Barn Tour](https://www.thewilds.org/rhino-barn-tour) on Saturday, February 28. The tour is scheduled to last 90 minutes. **What you need to do to attend** Signing up here on Meetup will not get you into The Wilds for the tour. You must go out to The Wilds' [website](https://www.thewilds.org/) and [buy a ticket](https://www.thewilds.org/rhino-barn-tour). Please [purchase your ticket](https://www.thewilds.org/rhino-barn-tour), then sign up here on Meetup so I know how many to expect. **Attendance cap** There are only eight total slots/tickets available for this tour. As I obviously have already bought one of the tickets, that leaves seven spaces for everyone else. If you are interested in this event, I urge you to [buy a ticket](https://www.thewilds.org/rhino-barn-tour) at The Wilds' website as soon as possible. Since their website is obviously public, nothing prevents other people having nothing to do with *GOhio!* from buying their own tickets, thereby potentially taking an available slot away from you. **Additional notes on attendance** I have now run several events at The Wilds. While the location of The Wilds and the pricing of the tickets generally leads to small turnouts, the people who have gone have all enjoyed it and were glad they went. If you've never been to The Wilds and you like zoos or animals at all, you are likely to find any tour at The Wilds to be a rewarding experience. **Tickets and pricing** [Tickets](https://www.thewilds.org/rhino-barn-tour) for this tour are $95, or $76 if you're a Wilds' member. I've posted screen shots, below, to help you be sure you're buying tickets for the correct event. Wilds' memberships pay for themselves if you go to The Wilds at least twice a year, and [Columbus Zoo members](https://www.columbuszoo.org/membership) get a discount on memberships to The Wilds. I will always run at least two events a year at The Wilds. Tickets for all Wilds' tours must be purchased at least 24 hours in advance of the actual tour. **Cancellations and refunds** Per The Wilds' [Cancellation Policy](https://www.thewilds.org/policies): *In order to be eligible for refund and accrue no rescheduling fees, cancellations must be made at least 14 days in advance of reservation. Cancellations made within 14 days of reservation will not receive a refund.* You may [contact The Wilds](https://www.thewilds.org/contact) at (740) 638-5030 between 10 a.m. and 4 p.m., or you can email them at information@thewilds.org. **Waiver of liability** After you purchase your ticket, you will likely be asked to fill out a waiver of liability. This is a very short document and should take you no more than two minutes to complete. **Where we'll meet** We will meet at The Wilds, whose actual address is [14000 International Rd, Cumberland, OH 43732](https://www.google.com/maps/place/14000+International+Rd,+Cumberland,+OH+43732/data=!4m2!3m1!1s0x8837dae07a595557:0xa1ceca93325a8bd1?sa=X&ved=1t:242&ictx=111). Please try to be there by 12:30 p.m. For most Wilds' tours, a shuttle bus will take you to the actual spot of the tour. So think of this as though you're going to the airport to catch a flight. It helps to be on time. The Wilds generally asks that people arrive at least thirty minutes because the scheduled start time of their tour. **GPS / Getting to The Wilds** The Wilds is in a very rural area, but I've never had a problem getting there with my GPS (I have Verizon). I've also uploaded a JPG map, below, of Muskingum County. Sometimes, though, it's hard to get a signal when you're at The Wilds and getting ready to leave. So you might want to consider downloading an offline map in Google Maps. Your cell phone should pick up a signal, however, within a few minutes after you leave. The Wilds' Visitor Center does have free Wi-Fi. **Carpooling?** If you want to carpool, I recommend discussing this in the comments, below, to this event. While I don't myself carpool, I will do what I can to help you arrange something if I can. **The weather** Dress for the weather. Just because the barn is heated doesn't mean it will be warm. And wear closed-toed shoes. Wilds' tours typically run no matter what the weather is. **After the tour** Once we're done with the rhinos, we'll head over to the very highly rated [Y-Bridge Brewing Company](https://ybridgebrewing.com/). The brewery is about thirty minutes from The Wilds, and it will be on the way back to Columbus for most, if not all, of us. The brewery's actual address is [1417 Linden Ave Ste D, Zanesville, OH 43701](https://www.google.com/maps/place/1417+Linden+Ave+d,+Zanesville,+OH+43701/data=!4m2!3m1!1s0x8837edd6cc50824f:0xe3a0af1ccb2aefbf?sa=X&ved=1t:242&ictx=111). Y-Bridge Brewing does not serve food; however, they have several [food options](https://ybridgebrewing.com/food-options). I encourage you to check these out ahead of time on their website for yourself. However, here are a few of them: *Within walking distance -- 120 feet away* * [Angry Bull Saloon](https://www.facebook.com/AngryBullSaloonZanesville/) (pizza & subs) * The Corner Pub Sports Bar and Grill (classic bar food) *Delivery options -- [Door Dash](https://www.doordash.com/)* * [4 Star Pizza](https://fourstarpizza.com/), (740) 452-9300 * [Donatos](https://www.donatos.com/), (740) 452-7900 * [Pizza Cottage](https://www.pizza-cottage.com/), (740) 455-6000 * [Dominos](https://www.dominos.com/), (740) 455-3126 * [Papa John's](https://www.papajohns.com/), (740) 450-4100 If you live in the area or can't make The Wilds but still want to meet us at the brewery, that's fine too.

Let's grab some coffee/food and share a morning chat! The East Market has an ample parking lot and outdoor and indoor seating. Grab a cup of coffee from Winston's Coffee & Waffles or on your way to East Market and meet us on the second floor - table behind or east of the elevator. If the weather cooperates we will be meeting in the patio. Per what this group is about: "Everyone is welcome! International transplants to Columbus who want to improve language skills, Columbus residents who want to discuss international travel and culture, and anyone who enjoys getting together for good conversations."

It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Here is the secret of being positive and free: Thinking positively is not enough. You also have to get rid of the negative thinking. Your mind is like a garden. You can plant many beautiful flowers in it, but if you don't get rid of the weeds when you plant your flowers, the weeds will soon take over the whole garden. A positive thought is like a flower in your mental garden, and a negative thought is like a weed. You cannot expect to have a positive mindset if you continue to have negative thoughts dwelling and growing there. So, how do you get rid of the negative thoughts? That's what this Meetup is all about. Attend this local meeting and find out! The Meetup event will be led by a consultant who had helped many people live happier in life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Dianetics & Scientology life improvement center.

Dale Gnidovec, Curator of the Orton Hall Museum of Geology at The Ohio State University, will be presenting a program he has wanted to share with us for a long time: Plate Tectonics. His description of his program: Continents on the move - Nothing in Earth history makes sense without moving continents - it tells us why mountains, volcanoes, minerals, and fossils are where they are. This talk examines the evidence for continental drift, why it was disbelieved, and explains how the more-encompassing theory of plate tectonics was developed and eventually proven. Dale is an energetic, incredibly knowledgeable, and very entertaining speaker and this will be another wonderful program by Dale. Hope to see you there! Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid. You can meet us in-person or attend online Join Zoom Meeting [https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1](https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1) Meeting ID: 878 3656 4953 Passcode: 760812 One tap mobile +19292056099,,87836564953#,,,,\*760812# US (New York) +13017158592,,87836564953#,,,,\*760812# US (Washington DC) The formal presentation will start at noon
