I have had the same intimidation issue as what's been described here...I want so badly to ride ride ride, but I'm nervous about the traffic (I'm kind of rural, roads don't have paved shoulders, but are VERY busy), yadda yadda yadda. So, I went to the LBS, and asked if a complete and utter newbie could join their Sat. AM bike rides (I was worried that I would be the slowest, most clueless person in the group, holding everyone back, or that maybe they just wouldn't let me go until I got better); ended up that there were people from every skill level there...some who were lightening fast, some who were just there to have a nice ride, and some who were just beginning like me. And, one of the bike shop employees hangs back with us newbies and guides us in traffic safety, shifting, etiquette, etc. It's been really cool. Anyway, that's a suggestion...find a group to ride with who accepts newbies.
