My husband, of course. We ride at the same speed, even though he can ride faster than me. But I have become faster, so he is happy to ride at a 14/ 15/16 average. He pushes me once in awhile and I hate it while it's happening, but afterwards, I appreciate it.
I also like riding with Denise G., but we don't get to do it often enough!

My most fun ride was with my (former) exchange student, who is a pro for a B level team in Germany. He did 2 twenty mile rides with me last summer, on his recovery days. I felt honored.
