I've spent lots of time driving from coast to coast, and between Alaska and Arizona, and I've made stops at numerous national parks and points of interest along the way. I'm finally getting more of the photographs from these trips organized into this virtual photo album, so expect the list of states to increase as I spend more time on this project.
In driving between Alaska and "the Lower 48" (which I've done a few times now), I've been able to explore a little of western Canada. I've also made a few trips to Dawson City and up the Dempster Highway during late summer. And while wintering in Arizona, I've gone on a few trips south to the Pinacates, volcanic mountains in northern Mexico.
