Something very unique about the Alaskan experience, you begin to meet fellow travelers at campgrounds in great falls Montana and continue to meet the same folks at other campgrounds down the line, unplanned. I would walk the two dogs early and late and had chance meeting with one couple in five different locations. Many folks will seek the company of a caravan, traveling together. Independents as they take the comen path develope acquaintances also.
The moral of the stores,,,be nice to people starting out, as you may well be camped next to them in the next village down the line..
