Other than fuel prices, one thing to remember, is school is going to run late this year due to the snow-days. Afer school is out, traffic will most likey increase. Maybe people might not run the boats as much, but they will go out.
I too, have the cheaper gas in my boat from last summer. I figure when I fill up at 1/2 tank the fuel will still be a bit cheaper until all of last summers gas is gone. At least I am training my brain to think of it that way.
