Probably a little late to the party no as your probably clear of the border by now but hope you didn't do the Hi 36 south from Taber route...last time I was down that way, even riding on 10 air bags the last 40 miles or so would jar your teeth out. Might be a half dozen lights going thru Lethbridge but it is still a much better "ride".
Thinking of the lights in Leth. and you going south to head east reminded me of your earlier post on Inter-states...gotta love them...60-70 MPH thru town centers past the court houses with the local Sherriff's that are hanging around, waiving at you as you go by.
If you do go south to Great Falls and then east...gotta stop at
Jakes Corner diner for Corn Beef Hash & Eggs...best in "merica" and Ive tried it all over LOL.
Did you have a "back haul" that routed you south...not sure I would have recommended that route if your just hauling Sailboat Fuel or Motorcycle doors for a way home this time of year...winter road maitainance southside in the winter isn't tackled with the same fervor as we do in the frozen north.
Again man safe ride!!!
