Nice bike there my friend - and welcome back to the world of bicycling - where ya been? hehe
We have a lot to offer here - if you haven't already prowled around - there's a 55+ forum, funky forum called Foo, and even some regional forums so perhaps you can hook up with someone from your area to ride with. Oh and since you're just getting back into it - do check out via google or asking your bike shops in the area about any bicycle action in the area - the clubs that I'm in have organized rides for people through out the riding months - and rides that are arranged for people range from beginners to medium (we call them Sweep rides here - as the ride captain rides at the back - no rider left behind) to the regular bike rides where you basically say Hi to the other guy and he takes off. Unless you keep up that is.
