alot of clunkers get snatched in philly... alot of cruisers and beaters... not to say it doesnt happen... but it seems more common for someone to steal something that makes you ask "why would anyone steal that?"

anyway... i lock up all the time with a solid u-lock and a heavy cable for the rear wheel on my road bike (quick release on both ends ofcourse) and for the kona i've been riding lately i lock the front and frame... so far so good (knock on wood)

but i dont keep my bike outside for more then a few hours at a time... and i always try to lock it on well lit, higher traffic streets
...
these are just the typical steps of precaution that were bestowed to me... but that seems to be the common philly methods
