My buddy Jo-Ann, because when we rode, we were about the same ability level, and would push each other. Well, she pushed me more than the reverse. But then we both got employed, and pregnant, and ...

Also my son, because he's so enthusiastic! But that's only short rides of up to 7 miles. Then he gets bored and hot.

Also our ex-exchange student, because he'd ride at my comparatively slower pace.
