Thanks for sharing - brings back memories; I grew up on the skidoo line, first on twin track single ski, then old TNT 775, black TNT440. Moved over to a 77 Panther 440 (love those cleats), then Polaris. Last one was a 2000 RMK700 136".
I sure like the looks of your new summit, with the 163" track.
It was always - "ride for one, fix for two" (insert "hours" or "days").
