One has been on location at mom’s organic market in college park md for at least a year.
It’s been a few weeks since I’ve been there but I’ve never seen it down, and everything’s always worked correctly on it — catapult, locks, stage, shaker, etc.
The pinball map does have a couple notes about it being down, but I don’t think it would stay there for so long if it wasn’t a reliable moneymaker.
I bought my Houdini after playing it a bunch at mom’s.
