Richard,
One solution I found was to forget about the maps and buy a chart / GPS. Solved a big problem for me.
Lake Hatch and Kiss and Panasoff and Istapog and Hernando and Okee all look one way in sunlight and something entirely different after dark, in the rain and late night fog.
I looked around and found a Lowrance M68 color unit. At $400.00 retail, this unit has all maps internal and requires no external GPS antenna. I purchased the accessory power plug and two mounting brackets. One for my truck and one for the airboat. Best feature for me at the "get home" track / trail feature.
It is no Rand / McNally Road map, but, it has surprising detail on our lakes and marshes. Has kept me out of trouble all over Florida. I also installed a marine compass and I keep an eye on that all the time, too.
