Hi, Skunk. I'm in about the same boat: just about to click over into the 50+ category, and hadn't been on a bike since the mid-80s. The kid at the LBS was very polite. He went and found me a nice helmet for my test rides when I asked for one, and when I came back after the first circuit and mentioned I'd made it over the speed bump without wiping out, he didn't laugh.

Hope we both enjoy the challenge of getting back into it,
Dagna
