I've been commuting during the winter for years but this was my first group ride. A little more challenging clothing wise since they go for a longer distance than my commute but they stop for coffee/hot chocolate half way through.
It was 8 degrees F when I left my house. We'd just gotten a snow storm that ended early yesterday but the roads and the trails were mostly plowed. It was a nice size group, - around 10. We hung around the LBS afterwards for waffles and conversation. I guess they're going to try and have them every Sunday morning. All in all it was a very pleasant way to spend the morning.
Anybody in the Minneapolis area who's interested: Leaves around 9:00 from the Midtown Freewheel Bike shop. The one on the Greenway. The shop is open at 9:00 on Sundays so you can stay warm until everyone arrives and is ready to go. It's a recreational ride, -no drops.
Oh, and Freewheel had a deal on studded tires, buy one, get the 2nd one at half price.
