Hey, my 13th birthday is at the beginning of November and I think i Have finally found out what I was going to do though. But I don't think a scavenger hunt at the mall is a bad idea, I actually think it is cool. There are two different types that I know of though. One of your parents could create a list of things you have to find in the mall, and you have teams or partners or something. Also, one of your parents could make a whole bunch of clues about where to go. They would start each team out with one clue on where to go. Like when I did this type, our first clue was, "Salute a sailor" so we went to Old Navy and got our next clue which was "Comfort like a Lazy Boy" so we went to the massaging chairs, and we had many more clues, and our last clue was "Coldest place in the mall" so we went to ice skating rink, and got our last clue, then we went to my coach with all our clues and she gave the winners a prize. I doesn't matter if you want to invite guys and girls, or just girls, it's up to you! I hoped I helped you a lot, but I'm sorry if I didn't!
