If you go over to YouTube, there's even a video interview with the man behind it, Juan Mann, who was required by the city to stop or take out a $25 million (yes, that's $25,000,000.00) liability insurance. A 10,000-name petition put an end to that. Thankfully.
Here's the video. It's uplifting and inspiring.
I hope you enjoy it as much as I do. It brought a tear to my eye.
