1.You guys go to drive-ins at night. Duh?
2.Eating while at the movie? If it were a drive in, I would consider it only if you could keep the nusance level to a minimum, like I wouldn't want waitress' walking around blabbing and stuff. Otherwise, I'd go to a theater where they had lazy boys over a theater where you eat at a table.
3.I don't now of any ways to make drive-ins new age.
4.I hope there is enough demand for one in your area. Anything can work with the right market. Americans are to lazy now, why go to a drive in besides a date, if you can just order your movies from the computer.
