Drive-in movie theater
Text from Facebook page: "Michigan's oldest Drive In with an all grass lot. Nice safe family environment! Movie themed cosplay events hosted often"
Text from DriveInMovie.com: "The Hi-Way Drive-in is a single screen drive-in movie theater located in Carsonville, Michigan. The Hi-Way Drive-in is the oldest of Michigan's drive-in theaters as it opened in 1947. It had gotten run down but then was purchased by Firebird Theaters in 1998. They have done much to revive it and as a result it saw increased attendance. They screen double features from Memorial Day to Labor Day using traditional speakers plus 89.7 FM radio. Current admission is $10 for adults and $7 for kids with kids 3 and under being free."
It looks like private events are a possibility based on content on their facebook page.
