I know of 2 drive thru liquor stores in Colorado. One is in Loveland and the other is on the Peak to Peak highway, near where we lived in the mountains (remember the chalet?)

There may be more of them, but those are the only two I know of.

There are drive thru beer distributors in PA but I've never seen a drive thru liquor store here. First one I ever saw was in FL, and they seemed to be everywhere down there.

Never seen liquor drive thrus either, just beer. We're all bible-belty and there isn't even a liquor store for 30min in any direction from where I live.
