Date Idea: Fireworks
Fireworks are great fun and can make for a cheap or even free date. Most cities have fireworks for free. Take some drinks and munchies, go early and find your spot, lay out a blanket or lawn chairs and wait for the show to start. Another fun idea is to make a double header of it. Go to a baseball game where they are having fireworks afterwards. It is a lot of fun to cheer on the home team and then share the fireworks with 20,000 of your closet friends. Of course the kids will like the fireworks as well.
