What about snow-bike rentals? Any local shops doing that? Looks like it might be fun to try one -- but I'm certainly not willing to commit to buying at this point.

PS regarding buying bikes -- I'm just now getting around to thinking about upgrading from my circa 2002 Rockhopper to one of those new-fangled full suspension bikes; or maybe even those big, fancy 29 inch tires. This probably means that I'm still ten to fifteen years away from buying a fat bike. Perhaps I'll catch-up someday.
