i don't think anything i have would make a good all around bike. maybe if i finish one of the utility bike projects.
if i could just go out and buy something that would hang in the underground shelter with the canned goods and piles of guns and ammo, i guess a yuba mondo would be my choice.
my other thought (in some real disaster/zombie apocalyspe type deal) would be if i could get to a walmart, or even a good lbs that still had bikes in it, grab several of the same model bike to have backups and spare parts that all match.
