Beautiful Weather; Poor Fishing

I don't get it.  The weather of the last two days has been beautiful, and I spent all day fishing  on both days in many different spot.  The result...not a hit!  Most of the ponds in the central part of the state are now ice free and that should have lit up the fishing, but it didn't.  I even decided to mix things up a bit and fish at night.  Last night I tended two rods in 50 degree weather (unreal) and not a hit.  I've prebaited most of the spots I fished so that is not the problem. I've seen no activity like bubble trails or fish jumping. I know it is only a matter of time before spring fishing breaks open if this warm weather and ice free conditions continue in ponds across the state.
