Actually no (in my eyes at least), I can believe that dean would have some explosives storied in the truck's stash, but I can't see him having easy access to a jackhammer.I thought the humor hear worked pretty well though Dean blasting the rock apart with C4 while *inside* struck me as ham-fisted. I don't know, maybe a jackhammer might have been over-the-top yet still a bit more reasonable?
