Sabine River ; Logansport, La - White Bass - around the middle of Feburary - World Class run. Lots of them and lots of BIG Sows. Some years are better than others, of course, but on the good years- I can't believe it gets any better anywhere than there.
Toledo Bend - May - Crappie move out on the flats post spawn. Drift along in 10-18 FOW. LOTS of em. Big too. Nice thump on that jig.
New River- Pembroke VA - I fished it two days and each day I caught a smallie > 20 inches. Nuff said.
Venice, Louisiana. October/November. LSU football/hunting season thins out the crowd a bit. Fish brackish water for tons of species. Flipping canes with soft plastics is big fun. Or spinnerbaits along the edges. Bring lots of spinerbaits, Redfish destroy them.
Ontario, Canada pick a lake. Walleye, Smallies, Panfish like nobody's business. Pike and Musky too. Go as soon as bass season opens.
Guntersville Lake for frog fishing on the matted surface vegetation.
crap I could list stuff forever.
