Played a family tournament at the Estes Park Golf Course, and when it began snowing, we didn't really think much of it. At one point, my friends father mentioned to me that my hair was sticking out straight from my head, and we all started to notice a decidedly "electric" feeling in the air. We boogied on back to the clubhouse, and just in time, as a major thunderstorm broke out right over the course. We hadn't noticed any lightning, just the fact that I looked like I'd stuck my finger in a socket. First and only thundersnowstorm I've encountered.
Played Lake Valley GC one late afternoon, and decided to finish even though it was dark. My friend and I both hit nothing but nine irons tee to green on the last four or five holes, and we'd simply listen for the ball to land and walk towards where we thought we went. Did not lose a ball, and scored decently, considering.
