I need some ideas for my son's 8th birthday party. He wants a scavenger hunt party that we will be playing just around our backyard. I wanted to divide the kids (boys & girls were invited) into teams and wanted some ideas on riddles for them to solve for them to go to an item to find the next clue. I'm new to this type of party! We will also be playing Capture the Flag, and other games so it doesn't have to be a long process (the scavenger hunt) Help!
