As most of us know, its a huge bitch to try and find people in the middle of crowds, or anywhere really. That said, I wanted to bring something that I could hold up in the air, like a stick with a crazy light on it, that could notify my friends where I am.
I was wondering what the limitations were to this... If anyone can help me out, that'd be great.
Additionally, if anyone has some good ideas as to what they would like to bring/make, post some pics! I think there are some pretty creative people on this board and it'd be cool to see what you come up with.
