Well sure.
If I was retired and had all the time in the world I wouldn't worry about making time. It wouldn't matter. My vacation reloads 2 weeks every year. :(
I'm not, and I do.
What is funny to me is the people that say if doesn't make any difference; bla, bla, bla. Aaaaaaaaaa yes it does. It's simple math. If I have a certain thing I want to see in a certain state I take the total mileage divided by the days I have and then get an average I have to go per day. If I drive slower, I have to spend more hours in back of the wheel. It's really that simple.
I don't mind driving, but I rather be drinking or napping or going to a museum or going to a park or relaxing near a lake. Not driving 50 or 60 MPH for hours at a time.
To each his or her own.
PS. I like #4! LOL!
