So a lot of kids and young adults hang around this Del Taco and raise heck. It used to be a big straightedge hangout. For some reason it's where fights happen in this town.
The drunk bro dudes at shorescrew.com have documented one pretty good Del Taco brawl for us: Del Taco Fight (page with embedded Quicktime video).
It's almost identical to a fight I saw in fourth grade except everyone's in their 20s and a vintage car is vandalized. Special attention to the really cool ape noises the guy in grey makes near the end of the barely visible second half of the battle.
