What you need:
- Strips of flagging {enough for all players}
- 3 glow sticks per team
- An open space
Tip: Don't play this with bright moonlight out, it really wrecks your night vision, making it extremely hard to see other people (not to mention the effect of your judgment).
Rules: Each player gets a strip of flagging to put in their right back pocket. Pick out designated sections of the field for each team. Each team gets three glow sticks that they can plant anywhere in their area. Once the teams break off, each team hides all three glow sticks wherever they want (using agreed upon rules like, visible at 90 degrees, from so far away, etc.). At some signal, teams attempt to find the other team's glow sticks. Once found, a glow stick is brought back to home territory and placed somewhere in that area with the same rules as before. You may carry as many glow sticks as you want, but if you are caught with them, you must drop all of them. To capture another player, grab the flagging that should be hanging out of the player's right back pocket (its important that this rule is followed so people know where to strike). When a team has found one of each color glow stick, they return to camp, having won the game. If teams wish, they can trade glow sticks if they agree on terms.
