Beer... and i'm not talking about tecate or bud light.. there are really good canned craft beers now.
1 Oskar Blues Gubna Imperial IPA = 4 tecates, which A) takes up less room, B) tastes a HELL of a lot better, and C) less trash
good canned beers:
all Oskar Blues (momma's pils, Dales, chub, tenfiddy, Gubna)
Ska products (true blonde, modus hopurandi, Special ESB, Utopia)
New belgium... well, if you have to!
lastly... buy from these companies and you keep your dollars local! (and out of the hands of the AB's of the world, that already own a 50% market share)
oh yeah - 5 gallon kegs make for a great boating option... just keep them out of the sun to prevent foaming.. temp. regulation is key!
