In the summer of 1986 I was at St. Andrews State Park in PCB for some very much needed R&R and had a few cans of beer with me in the cooler, and an open one sitting next to me, discreetly covered in the inevitable camo-patterned 'koozie'. In PCB they really have to monitor the teens and drunks or both, so I was a little bit scared, but not really surprised, when the notorious-for-being-a-hard@ss Chief Ranger stopped his blue-lighted ATV right in front of me, pointed and asked "Is that a beer?". I looked him right in the eye and replied "Yes, sir, it is!" "Is it cold?", he asked, perfectly stonefaced. "Yes, sir, it is!" I replied again, smiling widely, thinking how fitting it would be for the government to legislate only allowing hot beer on the beach. He then started up his ATV again and shouted as he rode away: "Well, you'd better drink it fast before it gets hot!" I still raise a discreetly covered can or two to his memory every time I have a beer on the beach.
Be discreet, be respectful, be honest and have a wonderful time.
