i like to be in the middle. right behind the fast guys and right infront of the slow guys. usually so if a cop comes after us either the slow guys slow down and stop and i keep going, or the guys at the front run and i stay behind while they get chased.
I ride with a group from work. Wide verity of skill and bikes. I have a trusted buddy who I organize most of the routes with. He has over 300000 miles sport touring and is very good at setting a pace that is comfortably for everyone, so he leads and I ride sweep.
