Signs every 20 ft would be a total waste of money. They would be ripped out of the ground... used for sledding... used to aide in telling sheriffs, F.S. employees lies that they didn't see any signs. Although, once in awhile you get the visitor who will say "what signs??? I didn't see any signs" as they are standing right infront of the sign you mention to them. I happen to know first-hand from my experience in the Big Pines Recreation Area that "I didn't see any signs!" is one of the first things that come to a person's mind whom regularly tries to work the system (I am talking any & all systems). It is quite a pathetic excuse if you ask me.
What will people with all these "ideas" ask next??? We should hire fulltime babysitters to stand guard over the lake 24/7 in the wintertime? Oh, well how about just drain the lake? Fence all around the lake? They will just climb over the fence. If you make laws many people will break them... if you put up barriers people will get around them... if there is a will there is a way.
Give me a break... it is time that people start being accountable for their own actions. People die everyday, all day. It is their own choice to make sound or unsound judgements. I believe they should also be held accountable for their unsound judgements. The persons whom fall through the ice should be charged for their rescue efforts. Just like they have begun to do when skiiers & snowboarders go out of bounds at Mtn High. As I stated previously the parents should be cited & held accountable when minor children fall through or go out onto the thin ice.
We go through this every winter... hundreds of people on thin ice, people trespassing, people killing or seriously injuring themselves sledding or skiing into trees, cars, over cliffs... driving up without chains & crashing their vehicles... breaking through locked gates... illegal parking... hindering emergency vehicle traffic... leaving everything they brought to the forest littered everywhere... graffiti everywhere, etc. The impact the Angeles Forest has from such a huge population base is one key factor. How can 2 or 3 people manage 1,000's & 1,000's of knuckle heads? Every new winter we have an instant replay of the winter before.
