We're not sure we'd agree with its claim to be "The World's Greatest Store", but if you're in the area, Miller's Surplus is well worth a visit. Opened in 1951, this hard-core outdoor lifestyle retailer specializes in military-style goods with a healthy dose of attitude. In addition to the expected camouflage clothing and multitude of flags, you'll also find plenty of bags, belts, boots, workwear, and tons of knives, as well as a copious amount of survival gear — pretty much anything you'd need for your next mission venture into the wilderness.
