Hey Jenniferh and Amy26 -
if you want to ride with other MS-150 people and don't mind the short drive, the BP MS-150 group rides a paperclip all year round every Saturday morning.
They welcome everyone, and you do not need to be on their team to ride with them. From what I hear, they often have new people on the ride. Feel free to PM if you want more details, I have a couple of friends on that team so I can ask.
There's also many MS teams downtown, most people train all year, while some take a break in the Winter.
Good luck to both on the MS!
