The "lake" is private property. There is private property situated between the lake and the public road. The fellow that owns the land offered to put up a fence but knows that it will be vandalized immediately. The government is hoping to acquire that piece of land and then develop the vocational college on this plot.
The police do go to the lake when they can spare the man power. But that isn't everyday.
I've seen 7 crocs at one time at the lake. And often over 50 people watching.
Yes, I think the boys are going to be in for a rude awakening one day, and I hope that I don't have to witness it (the lake is on the way to my house so I pass by everyday at "showtime."
