This weekend is National Farmers Market Week, and the Columbia Heights Community Marketplace is the host to some officials from the US Department of Agriculture. There's going to be cooking demonstrations, music, and educational activities for kids, plus a presentation about some USDA farmers market data.
The Community Marketplace is really a nice market if you've never been -- my favorite parts are the bakers and the sausage makers (which I guess means the butchers and the bakers, but not the candlestick makers.) There's also lots of produce, flowers, and craftspeople. Sometimes popsicle makers and others show up too.
The market is in the Columbia Heights Civic Plaza in the triangle at 14th, Kenyon and Park Rd NW from 9am-1pm, rain or shine.
