My conservation officer friend told me about a guy he found last summer. He was alone, and fishing in extreme heat during the day. He made it back to the small boat launch, climbed out of his boat, and was sitting there in the sun. He was in bad shape. He was lucky that the conservation officer found him, and knew what to do to help him. Now, the officer makes it a point to ask guys when he sees them putting in, " you guys have plenty of water?". This should be an annual thread. This season, I plan on hydrating the day before I go fishing, as well as when I'm out there. At my age, I may have to pee a lot, but I don't care. That means everythings working as it should. A-Jay has a good chart that shows the effects of dehydration. I'm hoping he can post it here as a reminder for all of us. Dehydration can happen to anyone, young or old. Drink up when it gets hot.
