Leaving at noon everyday will mean spending most of your time riding at night which means you'll have to slow way down to not outrun your lights. I'd invest in the most powerful lights your bike can handle.
There are SO many suicidal deer out there...no way I'd ride at night. Trying to stay focused and alert at night will sap your energy.
I'll take my chances with LEO's and traffic I can see over deer anytime.
Add more days, avoid all highways, taste the steak, see the sights, sit by a river, take some pics, live to tell about it.
I get walking directions on google maps and start from there. It's a crow flies route with no highways then drag route to twisty roads on the way.
If you're going to stick to the highways you might as well trailer it or buy a Goldwing.
