I would have to agree about the cold. Most parents aren't going to come out and take the chance of kids getting sick and missing school. Well, those that are not associated with a car any way. If they do come out they won't stay for the whole night. You'll start to lose your crowd shortly after the sun goes down and the colder air sets in. That causes left over food that didn't sell and paying concession employess to stand around. You'll get a better crowd in the summer months and have better concession sells as well. JMO.
