What is the purpose of this?
Congenital weirdness? The product of living in one, big outdoor squirrel cage? Or just something in the water? 
Gosh, that’s a pretty angry face there at the end of your OP, Bosda.
For all of the flack that New Yorkers suffer daily for being by turns dangerous, violent, uncaring, obnoxious, aloof, class-oriented, arrogant and completely incapable of mixing a decent egg cream, I think that the idea of an organized group event is kind of fun.
It’s pretty clear that the mobs are NOT being assembled to attack anyone, commit a crime or harass the local citizenry. Unless you consider mass shopping for a “love rug” to be harassment. 
If I had gotten an email about it, I probably would have tried to go and I would have taken the kids with me.
Yep. That’s right. The kids. Think about it. It’s very rare to be in a large group that ISN’T involved in some kind of negative experience. ( Rock shows and sporting events obviously excluded here ). I think they’d enjoy it too.
Looks like fun. I want in. Besides, I’ve been working on my Ruby-Breasted Sapsucker calls all summer.

Umm Pot? This is the kettle calling. I just wanted to let you know that you seem to be a little on the black side.
I want to sing up too.
Is this where to sign up for the Doper Mob? Where’s the riot?
Now that was funny!
Oh wait!
FWIW, I’ve seen way weirder than that. I’m from Philly, after all. Mummers Parade, anyone?
Sounds like fun to me. Anyone for a go in Las Vegas?
When I opened a thread in which Bosda is calling someone else strange, I expected to read about people getting naked, covering themselves with lard, applying pigeon feathers to their greased bodies and parasailing on the Hudson.
You can imagine my disappointment.
The article was entertaining, though.
