Hey Tom,
Great to hear you're looking to join a ride.
Look out for an email on this list (or make your own) for a day that fits your schedule. Here's an example ride call from Simon last week: "Tues 3/16 Skyline S2 0600 PPR." This guide explains what that means:
https://sf2g.com/primer.html. PPR means "Panhandle Peets Rollout" as Dan referenced.
The person who called the ride often gives a time and location for "intercepts" typically JFK & 36th Ave is ~10 minutes after the rollout and John Daly Blvd & Skyline Blvd is ~30 minutes after the rollout.
The Skyline route is popular with our friends who work at Apple (this list is public). It's a great ride.
Hope to see you out there,
Paul
