On my drive to town I always pass by an AMP and there's always a car parked out front. It used to never be this way. Even just 6 months ago I thought they closed for good since A: never a car upfront and B: they only had the open sign on maybe a few times a week. Seems like some new people, and a lot of them have gotten into the "hobby". Just know that the more popular it gets, the more likely I'd imagine a crack down to occur.
Stay safe.
