i have a friend that is from from anchorage... and she said that its hard to get to juneau.. because its an isloated city...
The only way to get there by highway is through Canada, and there's nothing particularly direct from there to Anchorage.
Also, when the Race most recently ended in Anchorage, the finish map was at an air strip that was well outside of the city. I recall it being something like 30 miles south. after teams had tasks in the city center and on the north side, IIRC.
I wouldn't be surprised if there's a similar pattern this time, and probably something similar to the finish a few seasons back in Honolulu.
