Commenters today raised some great ideas for DC USA’s completely unused parking level. Alex B. suggested we convert it into roller hockey or an indoor skatepark. Along those lines, maybe mini golf?

Bianchi had the cleverest idea of all: instead of building parking at the Zoo, let’s use that garage and run a free shuttle (or aerial tram) the 0.8 miles to the zoo (which would have the added benefit of enabling visitors to use the Green Line in addition to the Red). I’m sure the shuttle would cost less than the parking (above-ground garages cost $25-30,000 per space and over $30 per space per month for maintenance).

Any better ideas for how to use the empty space?
