I was riding through the loop at 9 pm Saturday and it took us almost one hour to go a few blocks. There were hundreds, maybe thousands of young kids in groups of 20-50+ roaming the streets, blocking traffic, overtaking the sidewalks. Some... of us went online on our phones to see if there was a flash mob planned for the loop because it was surreal. There were police everywhere, and at one point two dozen or more mini motorcycles swarmed and circled a gas station in formations. I have never seen anything like it in over 35 years of being a loop regular. It was chaotic, and unless it changes, nowhere I'd want to revisit!
