Need Suggestions For Beer Exchange. IPA. Stout. Porter

So Sunday is our West Whiteland neighborhood's 4th annual beer exchange. Everyone (dudes only) will bring a cooler full of beer and we'll drink some of it while we watch the Eagles lose. When it's time to leave, you load up you cooler with various types of beer from the various coolers.

Does anyone want to give any suggestions? There are tons of things I like but maybe I'll use one of your suggestions. Except nothing wheat or lambic. And nothing like Pumpkin Ale either.

My preference would be an IPA, Stout or Porter.
