Stuck on the Ice

This drawing was taken from a photograph in the Arctic near Baffin Island. The new Skidoo's were just beginning to take the place of the sled dog, however with a sled when things broke or a dog became injured or died, the owner still had at least half a dozen healthy dogs that would allow him to continue traveling.
Now if your sled has a problem you had better be able to fix it no matter what it is. Your life might depend on your ability to keep these machines running.
