Yuengling Beer... Very hard to find but the best damn beer on the planet!
Liqour... You will get tired of Jager. Everyone starts out Gung Ho about Jager but gets tired of it very soon. I'd stick with some high quality Tequila. Stay away from Jose as much as you can. Its not even real Tequila. I sugest Patron or Don Julio.
Mixed... Long Island Ice Tea; Its all I drink if I have a mix.
