My previous rants about using the word "POSTED" on a sign to denote "KEEP OUT" or "NO TRESPASSING" are here and here.
Another prime example:
From a distance, all this sign means is that the property has signs on it.
It's the fine print carries the real intent:
But the way I read this sign, running would be OK. See, I get the prohibition on hunting, fishing, and trapping...but then the sign goes on to also include "...TRESPASSING FOR ANY PURPOSE...."
Since we all know that Ultrarunning--which mostly is running long distances in the woods--is a sport inherently without purpose, then it must be OK to do it on property otherwise closed to other activities.
