The Anchorage Daily News
reports on why there are so many answers - so related to the changing route, others to technology, others to history... Interesting stuff.
No matter the "best" answer for this year's course - to be determined this year with GPS devices aboard a number of sleds - I'll be remembering "1049." Why? That's what Hobo Jim quotes in the song: Iditarod Trail.
Hey, Give me team and a good lead dog and a sled that’s built so fine
Let me race those miles to Nome, one-thousand-forty-nine
Then when I get back to my home, hey I can tell my tale
I did, I did, I did The Iditarod Trail
