Indeed. Now that I have a cable, I should get out and do some proper data logging (I too just got back from vacation ).That is interesting. Like you, I have a fairly decent elevation/temp change when I drive between St. George and Enterprise. (Enterprise 5500 ft. vs St. George 2200 ft.) I make this drive almost everyday, and have never really noticed much of a difference, but I have never logged. Now I'm curious. Maybe when I get back from vacation, I'll do a little logging, and we can compare notes.
I still need to do some research on how to properly log (best parameters/gear/duration of pull/etc).
