Congrats on the new ride and taking the MSF. I went through that last year at 55 having riden dirt bikes some as a teenager. I found the MSF harder than expected but was good experience. I would second the caution of large group rides. Went on one with 20 bikes fairly soon after starting to ride and the congestion at stops, small back roads, intersections, and group proceedures needed to keep everyone safe was a real pain. Would have been better to start with a small group of friends on a highway without as many stops. Good practice areas around here are local side streets that do not have much traffic, large church parking lots during the week or school parking lots on weekends. I put a 1000 miles on a light 250 before outgrowing it and getting a heavier bike. Found a neighbor that had a used 250 that has been passed around for people to learn on. Fun bike to learn on but not much of a major highway or traffic bike. Almost dropped it a couple of times at intersections and parking lots but very comforting to know its a used light bike and just put a foot down and catch yourself.
