Do you stretch first?

[7rider]

I ride with a group. I also belong to a gym. I've always been told to stretch and warm up before exercise, but only a small percentage of folks at the gym actually stretch and nobody in my cycling group does. Do you stretch before a ride??

Gulp!
I feel like I'm at the Dentist and he asks "Do you floss every day?"
Uh....

Well, I answered "yes," but I should probably add "mostly."
I also ride with a group, and we drive to the shop to do the ride. DH and I will stretch at the house while we're getting dressed, slapping on the sunblock, and loading the bikes. At the shop, we ride laps around the mini-plaza where the shop is to warm up.

After the ride, I'll stretch in the shower.
