Horse racing town

I guess when one thinks of Louisville and probably the whole state, he'd think of maybe basketball and probably horse racing, not necessarily in that order. We were staying only about 5 miles from Churchill Downs, so decided to take a walking tour.   Tour was ok.  It was worth doing.  Would have been much better if there had been racing today, but they are closed for summer (we were a week too late to partake). The place is really massive. I've been to tracks before like Penn National and Colonial Downs (and once upon a time the Preakness), but this was really a big place.  Pretty impressive.  They showed a 360 degree movie in a unique theater, had a small museum, and gave us a brief tour.
