1. Check out http://www.TossingGames.com My favorite is the Cornhole game! Awesomely fun!!!!!!
2. Capture the flag is always a night time favorite. You use clear jugs (milk, bigger water bottles, etc) full of water and drop a glow stick inside (a different color for each team). Then set up the boundaries and the rest of rules...it's so much fun!!!!
