Greg, the one thing I would be concerned about it putting in the number of long days you are looking at. You have probably put in long days with your folks, but it sounds like this will be you and only you on the trip. So, you have to do all the driving. Lots of stops to view lights will help you by forcing you to get out, stretch and get some fresh air. But, you need to take into consideration the strain of all that driving by yourself and have a backup plan in case you decide you need to stop for the day.
