Right now, I would say it was catching my first keeper last year, on my own plug made with help from Biteme, and Mr. Striper. I'm sure in 4-5 years though it's gonna be when my son Cameron catches his first fish ever, I think that'll be a day I am never going to forget.
In September several years back Eric LaFleur and I caught and released 28 False Albacore while wading the north edge of the north Island flats at Monomoy. We were flyfishing and all those fish took the fly in 3 feet of water or less. There were hundreds of them constantly crashing bait all around us as the tide rose. He got 15 and I landed 13 never mind all we dropped or broke off. Damm near ran out of flies with my PB being 12-1/2 pounds. 8 wt's with monocore intermediate lines.
I doubt I will ever experience flyfishing like that again.
