In one fell swoop, Blake Adams made the flea market more man-friendly — in a unisex, fun way — with the Denver Flea, which pops up in different locations and collaborations to suit the season while mashing up its merchandise with free craft beers at the door (to all who RSVP in advance) and good eats to cure the mid-shopping munchies. This is no garage-sale flea market, either: Quality vintage items and handmade crafts by local artisans are what's on sale, and those snacks come from a fleet of the city's better food trucks. And the fun doesn't stop there: Along with its vendor booths, the Denver Flea has built-in activities for all ages. This is definitely a market catch.
