We rejoin the Iditarod something like 48 hours in, and, on what sounds like a hard and fast trail, mushers are pacing themselves for the shorter 850-mile race. There've been a total of three scratches so far, none bigger than Aliy Zirkle, who suffered a concussion and upper body injury in the Dalzell Gorge and had to be flown out of Rohn by helicopter. Also, we catch up with our pal Zachariah Hughes in McGrath.
