One drive in here, the Boulevard Drive-In, has the 4K digital projectors, and claims to be the first drive in to do so. It is doing great business, with one screen, occasionally running theme nights, and engaging with the community. It is definitely worth checking it out if you are in the area.
There are 2 more drive-ins in the metro (one news report claimed this was the most active drive-in in any major metro today, but I never saw any substantiation for it); the Twin Drive In, which has two screens of course, and is fairly nice and in a remote, peaceful location, and the I-70 Drive-In, has 4 screens, and last time I went there many years ago, was a festering hole. I really want to go back to the Boulevard soon, and I'd like to go to the Twin again sometime, though it can probably use some updating.
