Only issue I see is that comment about biggest laker out of grand lake, when they meant biggest laker at a tightline tourney at grand lake. Likely a quote taken out of context which makes sense. Last time I checked that guy still won.
If the measurements are correct then that fish was right under the slot. I don’t think the tightline folks would fudge the measurements for fear of losing their permit. But… anything is possible in the age of misinformation.
