It looks like you hit the nail on the head. As I said earlier, I raised the fan thermostat slightly. This weekend I drove the car over 200 miles and the fan never came on while at highway speeds. As a matter of fact, the only time it ever came on was while stopped in some traffic. The temperature wasn't very high, upper 70's low 80's but normally the fan would have been running all the time.
My engine temp was 185 to 190, it never moved while on the highway and climbed slightly when stopped, probably to 195 then the fan came on. It appears that my "problem" was a simple one. I had the fan themostat set too low so that the fan was trying to bring the engine temp down to a point where the engine thermostat would begin to close. My engine actually runs cooler on the highway without the fan running. I have to assume that the fan was limiting the amount of air passing through the rad at highway speeds.

Maybe that water wetter really does work.
