Just about everyone does olympic level mental gymnastics during the winter from southeast Canada to Georgia. People are overly pessimistic just as they are overly positive depending on where they sit and how desperate they are for snow. Like you said, that's the purpose of the board, and it's what makes it incredibly fun and incredibly frustrating all season long. Most people strike enough of a balance to fit in, but we have our positive and negative outliers--God love (most of) 'em, no doubt about it.
My perspective has always been--just have fun. If you're negative, have fun with it. If you're a #faithinflakes kind of person, make it entertaining not obsessive. If you don't believe in fun, be educational at least.
Life is far too short and serious to be miserable here.
