I was night fishing with my son at res 3 one night, I was carrying. An Officer pulled in and flashed me with his light. He then got out and approached me, said he was just checking to make sure I was actually fishing and not some kids messing around. I laughed and said I hadnt "messed around" at the reservoir in 25 yrs! Then I informed him that I was carrying, he asked where the firearm was, I told him it was in a behind the belt holster, he said thats fine, wished me good luck fishing and went on his way. I was curious about it too because it is posted no firearms. But like someone else stated those signs are very old and do not reflect changes made to state law. I wouldnt worry about it.
