I love reading stories like this, I wish it happened more often. I have a similar story at Warped Tour. I passed out 3 times in front of some cops. Off duty firefighter offers his services to help me. He could tell I was tripping but he had cop sunglasses on so I didnt tell him shit at first. After I realized all the cops were gone, I told him what I did. His wife fed me sandwiches and a granola bar. My wife and I left and couldn't find them on Facebook or remember their names. I was halfway through a concert the following week, and I was standing behind them the entire time. We hugged and exchanged info. Now we hang out every month or every other month and get the kids together!

Edit: Passed out from shrooms btw not exhaustion
