howdy and welcome! Also try your state/city website (ok..that was confusing but for me its nmcycling.org). They should list all the clubs in your area and the ride types. Also, call several of your LBS - like Sadie said, they usually know of local clubs but I found my LBS' each knew a "different" group so I called several to try and get a complete picture. Good Luck and have fun!
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
