Greendale here. Happy to ride some time. Not aware of any club around here for Stromers or Adventure riders. I would go off road some time, but it would be a first. Enough just battling commuting traffic to and from New Berlin work days.
If any of you ride down by Lake Geneva or Kenosh, give a yell. I can throw a baseball into WI from my house and would love to join in on a ride. I, too, am willing to go for an off-road ride, but it would also be my first. I run up to Lake Geneva, Union Grove, East Troy, Whitewater, and surrounding areas on Sunday morning jaunts. Will post some pics of a relatively recent ride around Lake Genva shortly.
Sadly - my picture files are too large for posting on the forum..... Regardless, take a ride around the lake and you'll enjoy it. There are a few twisty roads with nice scenery (Snake Road), as well as the Fontana (?) Road that takes you from Williams Bay down into the West end of the lake where the Abbey Resort is. Enjoy if you go!
