South Glens Falls, NY USA

I was out on a bike ride with my brother and friends. When we went by the Sandbar Beach in South Glens Falls to sit on a bench to take a breather there was something on a lamp post. I went over to the lamp post and grabbed it and began to read it. Then I took it on our journey with us home! I told my mom and we looked it up online and found this website! I am 9!
