As a New Yorker I get asked that a lot: "Are you gonna do the 5 Boro Bike Tour?"
As a person who actually enjoys cycling, rather than standing around on the street straddling a bike with 32,000 other folks, ~28,752 of who haven't been on a bike in 4 or 5 years, my answer is almost always "You couldn't possibly pay me enough to do it."
(Which isn't entirely true; you could pay me enough.
But no one's made the offer yet.)
