Thanks guys. Very good reading. I travel and fish a lot of different water. My main fishing and my business is Flyfishing for Trout and Steelhead. I do other fishing and spring crappie is my second choice. Southern waters of Virginia seem to be 2 or 3 weeks earlier then my Pa location. Also smaller lakes seem to warm earlier and I think can be fished a little before larger lakes. I follow fly hatches closely and can relate timing of hatches, vegetation sprouting and spawning fish. Just my opinion.
