Replying to Why no indoor hills in the US?

I always see indoor snow hills in urban areas all over the world in other countries, but never in the US. Europe is filled with them. I think they would be extremely successful in the states. The year round aspect makes it much easier to gain profit. I think one is being built, or was recently built somewhere on the east coast, but I'm pretty sure that is it. Does anyone know why this not a big industry in the states? Do people just think it won't catch on, or are their other reasons?
