aah...sounds like the drawstring was the fatal error there...
when i lived in beantown, in the winters, i'd just throw on an old pair of nasty 80's tight black jeans (the sorta stretchy kind that girls and punks wore/wear) underneath my grungy, disgusting, holey, too-big-for-me volcom cargo pants. kept me quite warm AND!!! since they were tight, they never got caught in the chainring...that and i wear really long argyle socks...and my legs were hairy...REALLY hairy.
i kinda miss those black jeans...my ass looked GREAT in them and i got them for free from a thrift store because my GF was tight with the kids who worked there...gave them to the GF's best friend (who's all into the 80s and tiny like me) when we moved out here...oh well. i still have the cargo pants though. they look like i walked through a mud pit...permanent bike grease stains, chainring imprints, disgusting dirty water from the sludge that got kicked up from the streets all up the back (even with a zefal fender), rusty water stains, burrito juice, they just don't get clean in the laundry anymore, i think they gave up...god those pants are disgusting...but i won't give them up for the world.
