We may have seen the same Bighorn? We were traveling home today via I-15 and encountered a Bighorn traveling North on I-15 not too far from where you reported seeing one. We passed them and waived and a few hours later came across another Bighorn just as we took our home exit near Salt Lake City. I noticed one of them had a Utah Plate and the other looked like it was from "Alberta" Canada? I know our local heartland dealer ( not the dealer I bought from) indicated he is selling a "tons of bighorns and cyclones" so I'm sure I'll be seeing more and more Heartland products on the roads.
