No not necessarily.
Like i said i have been 4 times, 2-3 days at a time and had zero issue....my friends go 10+ times a year....no issues.
If you are wheeling with a group and you park your to watch/spot or whatever you will be fine....its not that bad.
However if you get stuck/break do not leave your rig unattended for any length of time....that's where issues happen.
A lot of the locals are extreme hill rods who's idea of fun is drinking beer and fucking shit up and they really don't care who that stuff belongs to.
