With the advent of online auctions, the whole world is a flea market, and a pretty awesome one at that. So if we go to a real live one, it better be an event. For the second year in a row, we're sticking with Elko Trader's Market. For one thing, there isn't a lot of new competition in the field. But even compared to the other far-flung established markets, the nationally recognized Elko mart still rates high. Because it's held on the three major holiday weekends--that's Memorial Day, Labor Day, and the floating Fourth of July to professional scavengers--it draws in more sellers (and buyers), creating both a buzz in the air and an extraordinary selection of antiques and oddities. Another plus is the indoor display space, which adds to the footage--and offers shelter from bad weather.
