If you plan to make it as far south as Colorado, PM me for campground and sightseeing suggestions. Just let me know what most interests you when traveling.
Do you know Sue Thomas, who frequently posts on the Alaska forums and lives just west of Whitehorse?
BTW, I also prefer the old US highways over Interstate highways. On the TX-OK-KS loop we completed yesterday, the only time we were on Interstates was within the city limits of Amarillo, TX. Besides US 287, we were mostly on US 62, US 183, and US 50 plus several state highways.
