I run into Ms. Pacs (and to a smaller extent Galagas), on location ALL the time.
One place in St. Louis that I know of operates (in addition to the ever present Ms. Pac), Tempest, Centipede, Sunset Riders, TMNT, Bad Dudes, about 10 EM pins, a cocktail pin, and an EM shooter. That is the only place I know of in the St. Louis area still operating a vector game.
I also remember another STL location (mall arcade actually), that had Space Invaders, Donkey Kong, Ms. Pac, Joust, Rush N Attack, DK Jr, and another 85' era conversion game that I can't recall now. I haven't been there in about 2 years though, I doubt the arcade or the games are still there.
