I reckon for me, it would be a farm pond that I had when growing up. It was probably an acre, and we were told it was 18' deep.
I was about 13 at the time, and I got my first taste of bass fishing there. I remember catching a bass on a crankbait, and one of the hooks got in it's eye. I didn't know what to do and started crying. I tied the line to a bush, leaving the fish in the water. Then I went up to the house and got mom.
She was irritated, as she didn't want to be troubled with such proceedings, rather, she much preferred to be perched on her chair in front of her desk with a cup of coffee in one hand and a Tareyton 100 betwixt the fingers of the other hand.
Nevertheless, she saw fit to get the side cutters and accompany back to the wilderness of our backyard pond.
She cut the hook that was offending the fish's eye. I unhooked the critter and put him back unscathed. Mom admonished me and said don't be fishing any more.
That was a turning point for me, and I've always remembered it. It made me want to learn all I could about how to unhook and properly handle fish.
That pond once yielded a fish that the adults to me was a smallmouth. They seemed excited... though I've never figured out why. It was just a fish to a 13 year old.
I always fished to the same spot, never around cover, nor what looking back would have been the better spots. I'd like to be able to work around it and all the dead stumps, the shallows, the tree lines.
Now, I'd start with the Spit'n Image. Then I'd move to squarebill crankbaits. Then, weightless trick worms. Might as try small spinnerbait amongst the stumps. Then I'd try flukes everywhere. And lizards... man.
