Woodbutcher,
Believe me, just because I'm getting the workouts in, doesn't necessarily mean I'm in shape!!!! I was just hoping to catch a few tips and hints.
As far as what kind of bicycle, a mountain type bicycle is definately the best bet, I bought the Gary Fisher because it came with a lifetime frame warranty (The Giant Iguana, the nearest competitor in 2002 was only 5 years). The reason I say this is because when you go to putting on yourself, (I go 225), the pack, (40 lbs more or less) and then meat on the rear, you're stressing that frame, big time. But then again, the bike was about $500. BUT it is alot lighter than the Wal-Mart bikes. But look at the cheaper bikes, at $80 use it a year, if you enjoy it, buy a better bike.
