I have a ton of amazing memories from when I was younger, but most recently, the one that comes to mind...
Late last summer I was spending the weekend in New Hampshire just to hang out and do some float tube smallmouth fishing on my favorite little pond. This pond has crystal-clear water (20'+ visibility), and you can see way down to the bottom where there are huge car-sized boulders mixed with gravel, grass, and sand, and there are two corners of the pond that are stumpfields with grassy bottoms and really weedy shorelines and laydowns. Perfect smallmouth habitat 8-)
It was a bluebird sky day, and the fishing was pretty hot all day (40-50 fish, nothing big). As the day was winding down, I was kicking around in one of the two grassy corners where the LMB like to hang out, just lazily throwing topwaters and plastics when it hit me. The sun was setting, the leaves were just starting to turn orange and yellow, and the only ripples on the lake were from my float tube. All I could hear were birds, and there was not another person in site, or on the lake. Then the beauty of it all hit me - I just stopped fishing, looked around, and just felt so content to be where I was. It's tough to explain - you just really have to feel it. Combine with that setting the fact that the pond is loaded with smallies and LMB who are more than willing to attack any offering, and you have heaven on earth.
Anyway, I think back to that day a lot, and others like it, and it's really tough for me to love that setting so much, but be stuck in a frozen tundra for 4 months out of the year. On the other hand though, it makes it so much sweeter when I'm actually able to be in that setting. Can't WAIT to get back out there in my float tube ;D
