*IF* you are shooting up the Mamquam FSR, then you have to be past the last Bridge.. 15km mark, aka 10 mile. You see the "You are leaving squamish" sign just before it. *IF* you are caught shooting at the Water tower, it is a $350. fine, plus they will seize your weapons. I was talking to the CO's last summer up there, when they were "talking" to a bunch of shooters, and there are signs all over the place that say "no shooting in this area".
Saturday Feb 20th, there were 3 Co's on Quads checking PAL's as well.
