My best day fishing is the first one that comes to mind. Then while reading the other replies, I got to thinking of some other great days, but I'll just share the first one that came to me.
It was almost 20 years ago, and I had started watching the fishing shows on TV. I don't know why, but seeing those guys catch bass just looked like allot of fun. I had never gone bass fishing before, so that might be part of it. I bought a new pole and a big selection of bass lures in a variety of colors.
I told my hunting buddy about the shows that I saw on TV and wanting to go bass fishing. He said they were biting at a local lake, and he was wanting to go that Saturday morning. We got there nice and early, then walked the path around the shoreline. He said they were spawning and was looking for them in the water. I didn't see anything, but he was spotting them all over the place. They were all small, so we kept walking.
About a mile down the path, he spotted a few that he said were pretty big. I looked and looked until finally seeing them. To me, they looked like there were about six inches long. I'm still not sure if I saw what he saw, but he told me to start fishing over them. I tried my spinner first. He laughed at me and told me to just use a warm. So after a few casts with that spinner, I put the worm on like I had seen on TV. He was still laughing at me, but I felt pretty good on how it looked.
It was a black rubber worm with a single weight. I over through it and was reeling it in and trying to get it over to where I saw those bass when it took off. The reel started spinning and my buddy went from laughing at me, to near panic. I don't know who was more surprised, him or me. I know that I didn't know what to do, so I just sort of stood there and watched the reel spin. Then the fish jumped out of the water and it looked HUGE!!
He told me to set the hook and start reeling it in. I pulled up on the rod and started reeling. He told me to get my tip down, so I did that too. I was about half way in when the fish jumped again and took off. I really looked big. My friend was a nervous wreck. In hind site, he knew what I had, while I didn't realize it at the time. He had the net and was half crazed by now, and was telling me to get it to the shore so he could get it in the net.
When we got it in the net and the hook out of it, I was impressed with how big it was. He was beside himself and said he'd never caught a fish that big in his life and didn't know anybody who had. He got out his scale and it weighed 12 pounds.
This was before digital pictures, so he took a full roll of film of me with it and I took another roll of it for my taxidermist. I already knew that he didn't want or need the original fish to do a mount of it, and since I don't care for eating fish, and with my friends encouragement, I released her back into the lake.
For whatever reason, only one of the pictures of me with the fish turned out. I've since come to realize that my friend is a great guy, but the worlds worse photographer.
We fished for another hour without a bite or anything. We really didn't care about it too much and called it a day pretty quickly.
My best day fishing was the day I caught my first bass, and the only fish caught that day.
