Omaha is, essentially, a military surplus outlet. They have uniforms, accessories, and memoribilia of all branches of the military. But the reason I like it is for the random, unique items I always find there. A friend of mine buys gently used fatigue t-shirts there (plain, army green) for $2 to $3 apiece. What a deal! If you're prepared for what you'll be dealing with, it's definitely worth a look.
