The Motor-Vu Drive in is one of the best ways to see Movies in the warm months in Utah. The Motor-Vu is the last of a few Drive in Movie Theaters left in Utah. Its a fun experience that everyone should do at least once in their lives.
The admission is $6.00 per person for adults and $2.00 for those ages 5-11. My daughter is 18 months so she gets in for free, but she obviously sleeps through the whole thing. You get two movies for that price. There are four screens but they discourage screen hopping. The movies are usually paired well. Get early to get a good location. Especially on weekends.
You may bring in your own food and drink. My wife and I like to bring in Pizza. We like to meet friends there. It makes for good times. They do have a snack bar and have popcorn and pizza and other goodies. Your typical move theatre prices though.
They pump the sound through a FM system so be sure to bring a radio if your car doesn't have fm. (Whose doesn't these days though?)
