Tuesday, I had not heard of the 2-2-2 system previously but find that's basically what I've been doing on trips. When I was in my 20s and 30s, I could drive 16 hours and more, but on my recent trip to WA, ID, and MT, I spent **5** weeks in total. You can do the math. Only a couple of days were more than 300 miles. I targeted nearby places to camp and sight see and did just that.
If you're traveling to enjoy yourself, then a big part is spending the time to visit local places, rather than blasting by everything on the interstate. That's not what this lifestyle is about. I have a great feel for where I visited in those 3 states now. And there are several places I wish I had spent even more time.
There is a difference between being a tourist and a traveler.
