Do you hear the sound through your radio? Or is it broadcasted? We would be first timers, so unsure of how this works

It's through your car radio and they also have radios you can rent for the night (I think it's $5)

Radio but it works out because you can change the volume to your preference

105.3 on your car radio or you can rent a radio for $4.00 in the Snack bar

Each drive in has their own station u tune into thru ur car radio. Only being in drive in area does the station work.

Yes you hear it through your car radio and the price you pay at movie theater you get two movies there
