Hey there! So I live in Colorado, and one of my primary goals tis year is collaboration with fellow YouTubers who are trying to make a career out of this. So firstly...hello! Good to meet ya.
Second - I have become keenly aware of the fact that there doesn't seem to be any organized group here. As such, I am going to be starting a YouTube meetup myself for the Denver/greater Colorado area. I know we're out here!
Keep watch on the forums here, I'll of course be posting when I put it together. Plan on sometime in September.
