My first group ride was at the Georgia Rally in '07. It was fun except for some old guy that kept slowing down going into the curves, making me run up all over him (just kidding Bucky...I don't think it was me)

Seriously, I don't know you or know anything about your riding ability, so I can't give you advice on what to do...but here goes. Please do what you feel is the right thing and the safe thing. Don't take your kid along if you're preoccupied with worry about this ride. Don't lead the group if you're that worried about it; pass out the information and let everyone know you'll be bringing up the rear to collect stragglers or something like that. If you really don't feel it that day, tell the group you don't feel well and you aren't riding. Only you know what you're capable of doing and what you really want to do. If you decide to do the ride, enjoy it; do it because you want to, and have fun with it.
