Eh, I'm normally one to criticize people for drinking shitty stuff, but when it comes to camping it doesn't really matter. Just grab a bunch of your shitty beer of choice and some good hard alcohol. Have a couple drinks of the good shit first and then start devouring those 24 packs.
That said, PBR is disgusting
I only drink the finest of shitty beers. Coors Light or Rainier
