Well Bassman,
If you are going to try to tour the country with your emphasis on the bottom right corner of a spreadsheet, you are going to be disappointed when you get home. While I have to be conscious of costs, I have fortunately decided that there are things that can effect my enjoyment without great additional cost.
There is way too much to see to be happy with just flying over it. Start planning now, get the guide books every where you can. There is a whole lot out there and if in the course of your 6K miles, you don't have a stop every day, then you must have missed something. In season, you will want reservations at places like Fishing Bridge, but other than weekend stops in attraction areas, just wing it.
We did just about this trip two years back, but from Michigan, it was only a 5K run. We did have to include some interstate but we did try to keep it to an minimum. We did have at least one stop every day. And only three days in Yellowstone. We had planned more, but I came up lame and if you can't walk it is hard to do much of that place. I want to go back when I can walk again.
This fall, we are planning to take Rt-20 from Toledo to Albany for my wife's 50th high school reunion. We are planning 3 days to do the 600+/- miles in three days. We have often done this run in a single day. We want to enjoy this one.
There are three quotes that if you don't have on a plaque somewhere, you (we all) should:
"And in the end, it's not the years in your life that count. It's the life in your years." - Abraham Lincoln
“Life is not measured by the number of breaths we take, but by the moments that take our breath away” - Disputed
Thanks to the Interstate Highway System, it is now possible to travel across the country from coast to coast without seeing anything. Charles Kuralt
I'm going to back out right here.
