I've never seen a fish that big let alone caught one. I'm probably one of the least successful fishermen around. I have plenty of luck trout fishing on a fly, but for any other fishing I pretty much suck.
In three years of sea fishing I've only ever caught one mackerel. And I hooked that fucker through his back. He was probably only swimming past. Which is a shame as I only live a 5 minute walk from the sea, but it gets me away from the computer now and again.
