I went on this cemetery tour with my wife and father and had a great time. Dreadful Dre was an awesome host, providing interesting historical insights into the buried dead as well as playful banter. Man, that last story was a doozy... Highly recommend if you're into history, Flagstaff, and/or the dead ;).
We parked in the big parking structure across from the cemetery, the walk was not strenuous.
