I know we all make our own choices regarding family, career, priorities, etc., but I've never been fortunate enough to decide whether to hunt or not based on the weather ....... I have to go when I have the opportunity. Yes, it's tougher at 52 than it was in my mid-twenties as well, but with no insult intended, I don't consider 37 and raining all that tough unless a long boat ride is included.
I remember 1989 on Catahoula Lake the opening of the second split. It opened on a Friday, and by Sunday morning the only open water was in the middle of the lake, and even then, skim-ice carried our decoys away. I've never been colder in my life than that morning on a near-frozen lake with temps in the teens and a north wind. Luckily, we were breaking ice a boat-length at a time coming out of French Fork, or the boat ride would have been miserable. Coming back in, we had to physically poke holes in the ice with the push-pole and run the boat up on it to break it ....... while Bruce Crain stood at the landing laughing at us.
I killed 2 greater scaup and a mallard that day, and I thought it all worth it. I'd do it again, but I've got better cold-weather gear today.
I hope the hunting today made you glad you were nuts enough to brave the weather!
