The District Department of Transportation (DDOT) recently posted two streetcar simulation videos of H Street and the Hopscotch bridge. DDOT held a public meeting to discussion the H Street - Benning Road streetcar this past Thursday evening but I wasn't able to attend because of another commitment. My girlfriend, some other friends, and I were on H Street yesterday and I can't wait for the streetcar to begin service next year (hopefully!). The H Street corridor is great and really booming, much like U Street a decade ago, but it is pretty inaccessible unless you drive or live near there (either a mile walk from the Eastern Market metro station or Union Station).
