WASHINGTON -- It's too hot to spend any time outside and have fun. Luckily there's inside fun to be had.

The National Building Museum is in the midst of their 'Summer at the Museum' series, special programming bringing in the residents and tourists to learn about architecture, play some games and cool off in the air conditioning.

One popular program at the Museum is their brand new mini-golf course. Opened earlier this week and available until September 3, the course was designed by Washington area based architects, landscape architects, and contractors at the top of their field. A handful of the designs can be viewed on the National Building Museum site -- and we've got some action shots for you to check out, too:
