The lake authorities and landowners don't give a flip about fishing. No fisherman or grass in the way of their jet skis or wake boats. Doug, I'll. Make the same offer if you can catch 23 lbs in 2 days.
Just because you cannot catch good sacks since the grass is gone, doesn't mean others can't get lucky. At that time that was the biggest sack that had been caught at Cypress in a couple years. The guy leaning on the boat behind us has caught a lot of big fish and stringers there duting and after the grass. He was one of the best out there for a long time.
Oh and I have been fishing the lake since I was around 10, so 45 years.
So to say it has not been done is straight
As for your challenge. I sold my boat and do not fish serious anymore. But I know some guys that may take you up if you made it a few dollars. 23lbs in 2 days should be simple.
Oh and if I drive down there to fish, I am going next door to fish.
