So, I have recently picked up a 16' X 12' Wegner stage that can be configured multiple ways. There are 6 8' X 4' carpeted stage panels and can be 16" or 24" tall. I have 2 organizations that will be using it in the next couple months. One is the local Art Guild, which I will not be present for and Relay for Life, which I will be there. I know I will have a certificate of insurance for the groups, since they are renting from us. But, does anyone have a release of liability or some type of contract where basically "You do dumb, it's your fault." Never rented anything like this before and want to be protected.
