Trip to Kaufbeuren, Germany and Fort Worth Texas, What beers should I get?

So I live in MA, but I am traveling to Kaufbeuren, Germany, and Dallas Fort Worth Area. Please give me some suggestions of awesome beers in the areas that I could take back with me. If you know exact locations of where I can find them that would be awesome as well. I will have a car and some free time so, if driving a bit to get these beers is worth it I am certainly game for an adventure. Thanks for the help!
