Yes, Milan could use to enforce their rules and have a security presence. They have security people, but you don't see them that often. Last year I was out there on a Friday bike night race, racing my KZ1000. I witnessed a few things that left me a bit concerned. First was a group across the pit lane from me and another group right next to me smoking pot. I don't have an issue with it as long as the guys racing were not partaking, but in one case I know they were. Another was a guy that paid to race and then was letting his buddies take passes on his bike. Lastly and probably the worst offense was a guy who rode up into the pit lanes, parked his bike, and then pulled a tall boy out of his hoodie pocket. I know I should have turned him in, but as long as he did not line up next to me I wasn't going to.
When I was just a kid I use to work at the track (in the late 70's). I know for a fact they were a lot more stringent about the rules. If you got caught drinking back then you have been banned from the track. The owners of the track at that time, Cliff and Barb Riley, were top notch people and really cared about things. I don't get that same feeling now.
