Here's what I'm planning: fly into Prince George, British Columbia. Rent a car in Prince George. Drive to Dawson Creek where I'll take the Alaska Highway all the way to its terminus. Then down to Anchorage, then back east, then south on Highway 37 and the Trans-Canada Highway back to Prince George, from whence I will fly home. The length of this route is approximately 3800 miles. I will have thirteen days of driving time. I will be leaving in the last week of June.

Thoughts? Opinions? Advice? 300 miles per day isn't too much to ask, is it?
