I've lived in Chattanooga all my life. I go to Riverbend almost every year. When I was in high school (9 years ago) me and a bunch of my friends went. As we walked in a cop approached me from my right side and grabbed me from behind my neck and escorted me to a trailer just beside the entrance. He pushed me up against the side and asked what I was doing. I said I came to see (insert random band here). He said you are not going anywhere with that knife sticking out of your pocket. It was maybe a 3 inch blade and couldn't have been been worth more than $10. He told me that I had to fill out this form and place it with my knife and I could get it back when I left. So when I left that night, I went back to the trailer to retrieve my "weapon". I asked for it and a lady showed me a large cardboard box full to the brim with knifes. There had to be at least 250 knives in there. Anyway point is, I have left my knife in my car every year since.
