Our formal is at a local banquet hall, kids drive themselves (they can get provisional licenses at 17, but no one bothers with the 1 passenger rule, including cops, since they’re so old already). The prom is at a huge fancy wedding hall, no one drives, just limos and party buses, that usually take the kids to the poconos or prom houses down the shore for the weekend. They used to have the formal at the HS, a lot more work, and the price was the same (around $60 pp).
