It's nice there, two shows for a good price. Where you park to watch the movie is gravel though, but is not like you will be driving more than 5-10mph on it. You park where you want to and can tune you radio station in to listen to the movie.
I grew up in Newton and enjoyed many nights going to the drive - in. Only thing that sucks is the trillions of mosquitoes but nothing that can't be solved w/bug repellent.
