I'll tell you two very good pies that I would've never even heard of much less tried had I not moved down southward (you'll NEVER figure out where, Rick) ...
1) Chess Pie
2) Millionaire Pie (Like this one better than Chess...it's outstanding!)
Both are "open air" so wouldn't work for DC, but if you like to make stuff or your significant other, give one or both a try. Millionaire you can do "no-bake" style.
