You figure with all the extra money spent on fuel commuting to work and around town then the extra fuel cost to get to the lake. It all adds up to a lot more than you think. Ya 20-30 more for your boat but add that to how much more your spending weekly just to run your car and you could be talking hundreds a more each month.
That will hurt anyone.
I have noticed less and less people passing us on our trek to Maine. In fact with my cruise set to 65 I was amazed at how many people we passed.
