It aint' about HSB, george, but it's sure about FISHIN'!
My daughter and I have been working on her 4-H Intermediate Fishing project, and Sunday it involved actual line wetting. We had great luck in only an hour, catching 1 RES, 29 BG (including an 8.5" immature male BG she landed that may have the best potential of any BG I have seen from our pond), and this pretty lady:
CC in my pond tend to be either silver/grey (females) or a dark battleship grey (males), but this female was a beautiful gold/green combination. Many BG we're catching this year are very similarly colored - I wonder if it is a pan-species camo adaptation to the prevailing water clarity this year???
