I dimly recalled reading somewhere about the technical term. Note to self: In the future, exercise prudence when using "mushing fan hook-up" in a Google search. The correct phrase is "fan hitch."
And it's a two-fur-one this week, as the season is rapidly ending for all things mushing-related. This next one was so much fun on account of the relatively obscure pun: I admit to feeling a wee bit childish + immature to drive personal satisfaction knowing full well how much of a head-scratcher some panels will be. Though there was some slight capitulation when an early reader that previewed the piece while at work had the excellent suggestion to include the periodic table symbol for lead on the dog-tag. Afterwards I was really quite impressed at just exactly how many folks keyed in on that hint - probably just as many science nerds as literary geeks out there.
