10. Go and see fireworks. As often as you possibly can!
Sure, there will be plenty of displays on the 4th of July for you to see. But many towns and cities also find other excuses to do them on other weekends through the summer. Find out when fireworks displays are going down (or, rather, when they're going up!) near you and take a date to see them. It's a cheap way for you to get the most out of a summer night.
