One of the other highlights of our trip -- the free McKinney Ave trolley! We used it to get to a fancy Italian restaurant for dinner. It's cool for several reason, one of which is the history of this trolley. This particular trolley has been in service around the world since the 1950's. In fact, as the driver pointed out to us the first time we accelerated, THIS trolley's engine noise was taped as the sound of the original Enterprise's warp drive engines for Star Trek! How cool is THAT?! :)   (19/22)
