2 cents,
Large events are a social gathering for me, Nothing more. I love seeing all the stuff. Crack down on the drinking and driving hard core. I mean really crack down on it and the bad element will start to go some where else.
Case in point Last year I made the mistake of checking out Potato Salad hill with my kids to see what the hype was about. 3 or 4 cops and tons of young people drinking(not what I want my 13 and 9 year old around). What can 3 or 4 do? Haul the patty wagon up there and set up a road block with a DUI check point. I like to drink but I do it at home or in my place of lodging. I get stupid when I drink as do most people. My judgement is not real good when I have been drinking and I can see where I might damage a trail if I was drinking and driving. TDS safari is a great example of the stupidity.
I like to spend time on Lake Mohave in a place called Gasoline alley. the LEO's don't screw around there. They come in every half hour see who's getting drunk and hit them hard on the way out. I have watched them go so far as to board boats and warn the drivers. 2 Hours later the idiots blow a DUI outside the canyon and its off to the pokie.
I don't care who you are a DUI is expensive.
Maybe not the answers to the problem but my honest opinion none the less.
