The perception is "its too hard". Its not and I found it fun. Ive a buddy who's a lawyer upstate NY. He owns the office building which has a shower, He's also a weekend and occasional weekday cyclist, has a 12 mile one way commute. I have expounded on the fun of bike commuting any number of times to him, his situation is pretty much a no brainer, yet he wont do it. Its really a case of just jump starting it and once he does it a few times, he'll get hooked. Its just getting him going is the hard part.
