They appeared to be a non-matching pair. Probably taken from a couple of snowmobiles from the looks of 'em. I didn't pay much attention as to the condition of the tracks - mostly just eyeing up the fab work and seeing how it looked like it'd work.
That little sucker has been up there as long as I have been skiing up in CB. I think its been for sale the last four or five years, it ran at least once. I saw it in town when I was like 13, outside of Mario's.
