Except for 1 rec group ride (about 18 miles) a couple months ago, all my mileage is solo. I'm planning on doing the group ride again tomorrow. Not a big fan of group rides though.

You should try the Seminole Heights Club rides on the second and third Saturday's of the month. The third Saturday is the best one. It's longer and goes through some nice areas. No pace lines or haul butt riding, just a nice leisurely 12 and 18 mile ride through Tampa, Hyde Park and Davis Islands. I normally ride solo but I like the change of pace once in a while.
