Come join us for a 11-12 mile ride at a Fairland. We normally average 10mph+. Wheels rolling at 6pm unless someone texts me they're running a little late. We normally do 10-12 miles. This ride is more for faster than average riders due to the pace. We wait up at intersections to let all riders catch up. If you have a good amount of rides under your belt and can average 8mph or better on singletrack trails, and take small brakes, then you will probably will be able to hang but it will be a challenge. About Fairland: 90% non-technical ride with few major climbs and no mandatory obstacles (they all have ride-arounds). There are a couple good places to stop and practice log-overs, and balance on the boardwalks, and some good flow trails. We will visit the skills pit but be advised, there are drops, jumps, skinnies, and overall technical features that will require the appropriate experience. Always take caution and know your technical ability limits. Video of our ride at Fairland: [https://www.youtube.com/watch?v=S1-b0EDVb08](https://www.youtube.com/watch?v=S1-b0EDVb08) What to bring: Plenty of water, helmet (no helmet no ride), your mtb of course!, multi-tool (although you can borrow mine), patch kit, extra tube (make sure it has the same valve you need for your wheel), a snack if you're doing both loops.

**Please join the Montgomery County Psychedelic Society for our monthly in-person psychedelic peer support.** This group is for those who have already had experiences with psychedelics and are looking to explore, understand, and learn from those experiences in a safe, welcoming space. Psychedelic integration is a way of turning the insights and experiences we have when we use psychedelics into lasting behavior and lifestyle changes. It’s a process of becoming whole, moving from altered states to altered traits. A psychedelic peer support meeting is a place where people take turns listening to and sharing their experiences, thoughts, and feelings relating to psychedelic integration. **Cost** Free **Location** * We meet in a private home in Bethesda, MD. * Street parking available * The primary bus routes servicing the intersection of Greentree Rd & Bradmoor Dr in Bethesda, MD, are the Montgomery County Ride On Route 30 (Bethesda Metro ↔ Medical Center Metro) and Ride On Route 47 (\~5–7 min walk) **This group may be right for you if you:** * Have past experience using psychedelics * Want to talk through your psychedelic experiences openly with supportive people * Seek additional strategies for continuing your integration process * Wish to support others in their personal growth within an inclusive and judgment-free space **This group may NOT be right for you if you:** * Hope that attending might replace your need for professional treatment of any mental health problems you might have * Are looking for group psychotherapy, medical care, or psychiatric treatment or advice * Had a challenging experience with psychedelics that continues to cause you distress * Want to find out where to access illegal substances or guides or practitioners working “underground.” **How it Works** Here are a few things to know about how our peer psychedelic integration group works: * Tea, water, and snacks will be provided * Please plan to attend the entire event. * Late arrivals and early departures disrupt the safety of our space. Doors will close shortly after 7 pm * There is a 15-person limit for this event so everyone has a chance to speak and be heard. * You must register via our MeetUp page. **Our Expectations of all Participants** To help keep our time together focused, meaningful, and safe for everyone, we ask that you abide by these expectations: * We treat everyone in our circle with courtesy, compassion, and respect, regardless of age, ability, race, ethnicity, national origin, religion, sexual orientation, or gender identity. * We do not encourage or condone any illegal activities, the purchase, sale, transfer, or use of any illegal substances, or partaking in any unlawful activities related to illegal substances. For those who choose to partake, we encourage safety and awareness from a harm-reduction perspective. * We do not use illegal substances during our meetings. * Please do not use the group for references to ceremonies or where/how to find illegal substances, online and/or in person. * Do not bring, buy, sell, transfer, or arrive under the influence of any illegal substances, or swap information on how to acquire them through the group, online, and/or in person. * Anyone who disregards these basic requests will be asked to leave the group and not be permitted to return. Thank you for respecting the safety of the space we are co-creating. **Finally** * *We ask that you not show up without registering.* * Attending these meetings does not create a treatment relationship. Any attendees requiring medical or psychiatric treatment will be offered referrals to professional care. * If you have accessibility concerns, please contact the facilitator via a Meetup message. * If you wish to speak to somebody about difficult psychedelic experiences and are unsure where to turn, immediate and free peer support is available from the psychedelic helpline [Fireside Project](https://firesideproject.org/).

This will allow us to scan and visualize a single atom - an ambitious we are doing over the course of a few months. The MoCo Makers community is one of the most innovative and competent groups in Maryland, and we've done everything from [publishing cancer research](https://pubmed.ncbi.nlm.nih.gov/38136356/), to [launching products](https://www.kickstarter.com/projects/gotim/cozy-curvy-multi-contour-pillow), [winning grants](https://covidinfocommons.datascience.columbia.edu/awards/2014255), and inspiring thousands. Now our biggest challenge yet has appeared. We are building a Scanning Tunneling Microscope, that will allow us to scan and visualize single atoms. To get a better idea of what we are doing, see our reference project here: [https://www.youtube.com/watch?v=7N3OqTEq08g](https://www.youtube.com/watch?v=7N3OqTEq08g) All starting CAD, code, and reference files should exist.
