SECURITY?
I've been going there every year since 2001. Usually arrive very early morning [before 8am], park near the lower gate, watch participants off-load their cars & bikes, watch the judging, the prize giving, the finale dancers... and leave at around 4pm.
All these years, I've never had any incident...touch wood.... so I never worry about the my car....
There is always a very large number of BM guys at every corner.
Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.
