Sure there are. Just make sure you find someone with the same size skates as you wear, swipe the bag, and voila.
I guess that could happen. I also chatted with an older man a few years ago who had borrowed skates from one of the Griffins for the post-game skates. He was the Griffin player's father-in-law. He was in town visiting and his young grandson wanted him to go out on the ice with him after the game. But unless you have similar connections, best to bring your own skates.
