Pastries, Cliffs & Ocean Views: SF Urban Hike

Join us for a relaxed San Francisco urban hike combining neighborhood streets, coastal trails, historic sites, and big Pacific Ocean views. We'll kick things off at Butter Love Bakeshop in the Outer Richmond, where we'll grab some baked goods and coffee before setting off (we'll wait until 9:45am for any late arrivals). From there, we'll walk toward Sutro Heights and make our way through the Land's End area, after which we'll finish by walking toward Sunset Dunes for the final stretch along San Francisco's oceanfront. This is a casual-paced hike. We'll take our time, enjoy the scenery, stop for photos, and give everyone a chance to chat and take in the views. (Dogs are totally welcome!) Looking forward to the event! Please let me know if you have any questions. 628-236-9369

Bocce Ball Bonanza!

No walk today unless we want to do one late in the evening. It's Bocce Ball Bonanza! We will meet at the Bocce Courts at Joe DiMaggio Park in North Beach. 1 of our members has Bocce Ball equipment that they will bring, We may also try to get some Pétanque equipment. Bocce Ball is Italian in origin and Pétanque is the French version. So maybe we can have some friendly competition; Italy vs France! Please bring food and drink to share. Bring a cup or prepare to purchase one. I looked into reserving the Bocce courts, but can't figure out out how to do that, but the word is that no one is ever there in the evenings. So we should be good, but there are no guarantees. Also can anyone can bring camping lantern(s) because the courts are not lit. Hope to see you there! Please note: Phone help is not available for latecomers. If you are late it is very hard to catch up with us. We walk at a medium pace. Escorts or sweeps are not provided, so slower walkers should be completely prepared to finish the hike on their own if they become separated from the group, and they may want to consider bringing a friend to walk with them. I reserve the right to make small changes to the route as needed. Liability Disclaimer: The organizers of this meet-up are unpaid volunteers and not expert hiking guides. All participants agree to assume 100% responsibility for their own safety, conduct, and well-being and recognize that possible hazards exist while participating in outdoor (or any other) activities, and agree to participate solely at their own risk.

Sunday Kickball @ Bushrod Park!

BASS presents our favorite event, kickball! We will be at our normal spot in the East Bay at Bushrod Park in Oakland! Bring your soccer cleats (for better grip on the field), sunscreen, and athletic wear and water for a fun time out! For those who haven't played kickball before, the rules will be explained and demonstrated before we start. Depending on the attendance, we'll either have 2 teams facing off or a rotation of 3 teams all together. Then after we may hit the local pizza/bar scene if everyone still wants to hang out. We have a HARD START at 1pm, so please be sure to show up on time for warmups! (We also nearly lost the field previously because not enough people were there on time) See you there soon! 🔴 Note: Please, please, please don’t no show. 🙏 It makes these events really difficult to plan. If you no show once, you will be given lower priority for future events. The second time, you will be removed from the event list for any attendee limited event we host.

Tam State Park Science Quest Day. 19 Free and Unique Events over one very full day. Experts in Fire Science, Lichenology, Botany, Ornithology, Geology, Hydrology, and Astronomy provide in person experiences to highlight how science can deepen our understanding of our environment. Sponsored by Friends of Mt. Tam in Partnership with California State Parks Come learn about the small and cryptic world of lichens! We will meet at the Rock Springs trailhead, and walk a there-and-back-again trail to meet some of the charismatic lichens of the area. These grow on rocks, trees, and on the ground. Participants will get to know certain lichen species, as well as lichen growth forms, and lichen ecology. The hike will be easy to moderate, with frequent stops to look at lichens. Bring a magnifying glass or hand lens if you have one - lichens are even more fascinating up close! Dr. Klara Scharnagl is the Tucker Curator of Lichenology at the UC Berkeley Herbarium. She is continually fascinated by the lichen symbiosis, and the many forms that lichens take. Her emphasis is on lichen ecology; how lichens respond to and interact with their environments. Lichens remind us to take our time, and to look more closely at the world around us. **GENERAL THINGS TO KNOW ABOUT SCIENCE QUEST EVENTS** **CAPACITY:** Only RSVP if you are able to attend.

FleetWeek, AirShow aboard the cutter Cetacea on Sat, Oct 10!

The cutter Cetacea (latin, marine mammal-dolphins/whales), a beautiful, strong, and well-appointed 42' blue-water sailboat with extensive operational and safety systems, invites a few crew aboard with a highly experienced skipper and platonic-only water sports enthusiast and science/technology entrepreneur. Strong preference for adventurous crew, as can be seen in the various photo albums of crew on more than 140 no-cost personal sailing adventures the past 9 years! This event is for women that prefer to sail with other women; sorry guys but there is a big demand for female-only sailing that isn't being met. Sailing experience isn't necessary, but enthusiasm for a fun, safe and exhilarating daysail, is! Yayyy,,, the **USAF Blue Angels** are back!!!! We'll slow-sail around the North Bay while gawking at **[big ships](https://fleetweeksf.org/events/parade-of-ships/)** and then hover near the flight zone for 3 hours of exciting flybys! You can view the Official **2026 FleetWeek** ship and Airshow info **[here](https://fleetweeksf.org/air-show/)**. This is an adrenalized fighter-jock sightseeing show, not a substantial sailing experience, and so we'll have a larger crew (6-10) than normal with a lot of sitting, eating, drinking, photographing, and ogling the aerial displays! If calm waters then we'll rig the Spinnaker swing! Please join the waitlist and experienced Shetaceans have priority for this **[event](https://fleetweeksf.org/air-show/)**. Please note that parking is very limited at the marina and you'll probably have to park at Pier 34 and walk the short distance (1/4 mi?) to SouthBeach marina. I'll send an agenda with clothing/food/parking/other info to our crew by Mon, Oct 5. Please be sure to rapidly respond to my emails to you, via your meetup account, or you will be summarily scuttled in the "Not Going" zone of abandoned flotsam, jetsam, and tidal detritus :-0

Experts in Fire Science, Lichenology, Botany, Ornithology, Geology, Hydrology, and Astronomy provide in person experiences to highlight how science can deepen our understanding of our environment. Sponsored by Friends of Mt. Tam in Partnership with California State Parks Mt. Tam has many microclimates, and its location near the convergence of several different ecoregions (North Coast, South Coast, Central Valley) supports a wide diversity of plant communities. Rock Springs is a great place to explore mixed evergreen forests, grasslands, riparian forests, and serpentine barrens. We’ll meander through these plant communities, discussing and identifying some of the plants and ecological processes that characterize them. Our walk may cover up to 1.5 miles, and you might want hiking poles for several short rocky/steep/off trail sections. David Edelson is an amateur naturalist. He retired from a career focused on environmental advocacy and land conservation, most recently with The Nature Conservancy. He has led field trips for local chapters of the California Native Plant Society as well as Marin Audubon Society and Golden Gate Bird Alliance.
