I started commuting again 3yrs ago. Haven't had any problems. As for they people who ask why I can't be "normal". I laugh, pat my stomach and say 'cuz I'd be 250lbs if I didn't. If they laugh with me, fine. If not, so be it.
As far as work goes, they get some kind of kudo points (don't ask me, don't know, don't really care, I ride for myself) for people doing alternative commutes. To get the points for 1 person that person only has to ride in 1 day a week and not even the whole commute. I ride in almost everyday. (It is Phoenix after all.) So the boss is happy to count 1 more alternate on his point system.
