Alright, here is mine...
On this specific day the weather was miserable and cold. I had a friend with me who was trying to learn to throw swimbaits but he'd never even seen a fish landed on them. Anyways, I saw a school of big bass in deep water, left the area for a while, snuck back in along the shore, ditched the boat, and laid a perfect cast across where I thought they should be, and BAM!!!! It was perfect! While not a 10 pound fish there is nothing wrong with a plan coming together and giving you an 8.9 lber!
