Dog teams have largely been replaced by snowmobiles (or snow machines, as they are almost universally called in Alaska).... Snow machines, however--for all their breathtaking ability to go as fast as fifty miles an hour over roadless terrain--break down now and again, and are thus perilous. A stranded traveler cannot eat a snow machine. Dog teams in the region are increasing in number, and the take of salmon is growing as well.
I wonder what Sarah is doing now.
