Hi Karen and welcome to the club
Would I be correct in guessing that the other members of the bike club own sports / road bikes as opposed to cruisers?
You could meet your fellow members at the destinations but ride there on your own, the best of both worlds perhaps, or maybe not, if they don't ride WITH you, leave you standing so to speak, then maybe your better off without them.
Perhaps you could join a 'cruiser owners' club. I know cruisers go fast too, but they don't seem to be ridden as hard as sports bikes, IMHO, so perhaps you'd enjoy the rides out more?
and that's the point, to ENJOY the ride.
If there isn't a cruiser owners club in your area perhaps you could start one?
Good Luck
