I've seen tons of kooky shit going down here, but the worst, in my opinion, is the fuckers who bring their 40lb RC cars to the park when it's at its busiest. Constantly cutting people off, coming way too close to causing severe injuries, etc. Just in general not giving a fuck about anyone but themselves.
Few weeks ago, same dude shows up to the new-ish park here, sees that it's packed to hell with people skating and children being children, and proceeds to start tearing around the park like no one is there. He ended up cutting off a buddy of mine, nearly caused him to fall face first into a rail. My buddy, who is generally a quiet and mild mannered dude, finally has enough and says something to the guy. Words were exchanged and I assumed that would be the end of it until minutes later I hear "Oh shit!" and see them going at it on the other end of the park.
My buddy gets a few good licks in and tries to grapple dude to the ground and just diffuse the situation, but RC dude isn't have it and proceeds to try to pull a gun. RC dickhead's girl runs over and snatches the gun from him while roughly 30 of us crowd around to make sure nothing escalates. Dude finally breaks away from my homie and starts yelling some bullshit about how we're all a bunch of pussies and whatnot.
Situation ends with all of us forming what is essentially a giant wall of people and running them out of the park. Haven't seen them since and hope they learned their lesson.
Sorry for the longwinded story.
