That's kinda what I thought.
It's gotta be a pretty fish, in a pretty place, and if there's any mud or anything else around that might get us dirty then it needs to be covered with concrete.
Dirty water is scary business! If you can't see what's in there then your taking you life into your own hands by getting close to it. Crocodiles, Sharks.....WHO KNOWS!
SHEEEZE! Trout purists are such pansies
