Yes it is called Backyard Maze 2.0 and I automatically watched it. Now I am in a wormhole in this guy's channel. He has some amazing work! He is a lesser chaotic version of Michael Reevers.
I am going to try that when spring comes around. I mostly see them in Gorky Park, which is both a public park and houses a lot of squirrels. I think it will be harder since there is always a crowd there. But if I do get one and it lays on its stomach and looks at me, I'll call it a win haha!
Hahaha... yes, looks like i'm going to have to check out more of that dude's content. Park squirrels are usually less afraid of people than usual. So, perhaps you can get some winning in soon! Cheers =)
