thirsty friends

these two 20 something chaps were heading from LA to the grand canyon on a cross country tour of the united states. because of a heavy language barrier I only gathered select information; they were from japen and wanted to know where they could "find beer"....more specifically they wanted to know "where can we find best beer in grand canyon"? unfortunately, being the sober gal I am , I couldn't help much, but assured them there must be beer somewhere in the grand canyon....right?
