There actually is a sign at the intersection of routes 37 and 16 in the British Columbia town of Kitwanga that reads, "North to Alaska." When I passed that sign with Sonntag in 2000, I thought it would be interesting to head up to Whitehourse, Yukon, and then to Alaska that way someday, instead of the only three other routes, the Alaskan Highway (AlCan), the Yellowknife Highway, of the ferry. This is the route I plan to take this year. Check out a Google Earth image of this sign (above), or block copy and paste the above geographical coordinates into Google Earth and "fly" there yourself.
