Thanks for the advice!
Thanks to all your great advice I tried on a bunch of helmets and got one that accommodated my small head and ponytail! I learned to change a tire. After several rides, i know I have to get some brighter colored clothes (those trucks are scarey). I'm using my weight training gloves for the time being, until I get some "real" ones. I was proud of myself for making the transition to clipless pedals so easily. Only one fall! My conditioning from spinning and running seems to be helpful, so I have been able to keep up with my more experienced friends, except on the downhills (I'm basically still a bit cautious). How do I get better on the downhills?????
Thanks everyone. I appreciate this message board lots.
