At a pre-dawn, air temp. of 16 F. at the house, the wife and I almost said, "No way", but after waiting for a bit; we decided to give it a try…Glad we did. Slow at first, but with the rising air temperature, I got my first bite and with some fun, I was able to bring a bright 21" rainbow to the net. I ended up with a second fish of 19" and the Wife one of 20" before some too loud noise pollution caused us to quit. A nearby angler caught four nice fish, just after I caught my first one.
