Two things stick out, one in particular.
The first and more minor of the two was a gaper who lost his board on the slope at Loveland, it took off down the slope and ended up stopping dead center in the pond, literally on thin ice (this was probably mid-November at the latest). This dumbass proceeds to start across the ice after it when the whole chair lift exploded with people screaming at him not to do it. I simply sat there quietly willing to let natural selection run it's course. The gaper eventually backed off and went to get patrol.
The 2cd was also at Loveland. I was riding Lift 6 and a couple of kids, I'm guessing 14-15ish were throwing snowballs at a couple of their buddies and accidentally hit a guy on the chair behind their buddies. Dude goes ape shit, cussing, raising hell, threatening to beat their ass, etc. Wow. I mean, yeah, the kids were being dumb and hit you with a snowball, but really, all that? Anyway, I get to the top and unload and this dude is just fuming, raging fucking mad. Irrationally mad. He was about 40, overweight, and probably hated his life and was bound and determined to take all that frustration out on these couple of kids. I decide I better follow along. He gets down to where the kids were waiting on their buddies, rips his board off and he's ready to fight. For real. Wow. I arrive on the scene just as he's pushing one of the kids over while both kids were still strapped in, not realizing that they need to be ready to physically defend themselves against someone who is quite possibly a fucking psycho. I slide in, rip my board off and pretty much tell the guy I'm gonna beat the fuck out of him if he touches these kids. Having another adult on the scene, he immediately starts pleading his case and I simply tell him that I saw everything that happened. Yeah, they accidentally hit you with a snowball, you cussed them out, they apologized while you were still on the lift and that should've been the end of it. No way am I letting you physically beat the shit out of a couple of kids. He starts to simmer down and I tell him to ride on. I tell the kids that I realize they were just playing around, but they gotta be more careful because there's some crazy fuckers out there and they just encountered one. I rode to the bottom to back them up as they told patrol what happened and patrol pretty much told them the same thing I did. I never saw crazy fucker again and I don't know if patrol caught up with him or not.
