Outdoor markets are found everywhere. People just set themselves up anywhere there is traffic to sell their wares. We are told that there is no necessity for a license or permission of any kind as long as the selling place s not permanent.
Some markets are semi-permanent with such booths that probably are rented. We frequent these open booths where produce is sold We also like to just walk around and see what is for sale, how the wares change as the seasons do.
