I often ride on the bike path in Redondo, Hermosa and Manhattan Beach. Its mostly cruisers but many time serious cyclists ride it. On more than a few occasions riders have gotten on my wheel and hitched an easy ride. I dont mind this at all.
Recently because I have been in shape I will grab onto a riders wheel if they pass me and I try to keep up. Sometimes me and the other rider will have a good back and forth pull effort for many miles. However, on two occassions a rider has turned around and yelled at me and asked "what the f do you think your doing, get off my wheel"
