"Cold" weather fishing

The cold weather you folks at home in New England have been having has also invaded south Florida.  Although "cold" here is a bit different than cold there.  In any case, the Gulf water temps are around 60F and the fish are sluggish.  They like 70F and above. The best places to fish are the back country shallow water around mangrove islands and water discharge areas of power plants.  On Friday Stan and I rented kayaks and fished the inside islands near the mouth of the Caloosahatchee River in Fort Myers. This is across San Carlos Bay from Sanibel Island. It is the closest place for us to do some fishing and a place we have been wanting to try.  It was fun kayaking through narrow mangrove tunnels and looking for fish.  We had a few hits in some of the deeper channels between islands, but no hookups.  Then on the way back we were fishing the deeper boating channel and Stan had a couple redfish follow to the kayak and take a whack at his fly, but still no hookup.  I had the same thing with a good-size snook, but still no hookup. It was a fun trip and we'll be back when the water warms about 10 degrees. Next time we'll try the Orange River near the power plant discharge area.
