When is the flea market open?

Most flea markets are open only on Saturdays and Sundays, usually from 6 or 7 am to as late as 5 or 6 pm. In Arizona, where it becomes quite hot by noon, there are flea markets that open as early as 4 am.! Buyers will come equipped with flashlights. By noon, many of the buyers and vendors have already went home because of the heat. In northern climates, many flea markets are indoors, and have regular business hours, opening around 8 or 9 am. and staying open until 6 or 7 pm., and some are also open on weekdays as well. I am a professional flea market vendor and make a very good income just working weekends.
