Here is a good compellation of rides for the upcoming year:
Which one(s) is/are on your list to do? Which have you done in the past with good experiences and would recommend to others?
For me Muenster Germanfest is a must do annually. Lots O hills with food, music and beer afterwards.
I think I will add The Wildflower Bike Ride. This one has a HUGE turnout but the festival is a tad pricey.
Ride for Heros is a great training ride with monster climbs and as if that was not hard enough they added a 100 mile distance this year
