There is a 50-something guy in my city who commutes to work most days over 20 miles round trip who does it on a recumbent (sounds like a good bumper-sticker: "I do it on a recumbent!")
I commute 30 miles round trip on a "wedgie." Not that I prefer an upright, but I just haven't bought my recumbent yet, which I really, really want to do when I can.
I was amazed that nobody who posts in "Commuting" or "Open Discussion" or "Advocacy," etc., really rides recumbents. I think you guys over here ought to do some "Public Relations" work over there. I think too many cyclists are missing out! (You folks are hiding a good secret!)
Anyway, it's up to you!
