I once went into Colorado to pick up a scraper in the Trinidad area, Dot guy at the POE in Grand Junction suggested I could save time by going over Monarch pass to Pueblo... I wanted to shoot him when I got there. I had a Cozad with a 3 axle jeep, a 3 axle lowboy (long) and a 2 axle booster. I swear the trailer rubbed the mountains on some curves, and I ran into a huge herd of cattle being driven on the highway... no I didn't hit them but it sure slowed things down. This was in October, when I got to the pass the snowbanks were already 6' high on the side of the road. Oh, my KT Cummins was gasping for air too, lotsa black smoke.
The rest of the trip went well though, From the pass down it was smooth sailing, I loaded out in Trinidad and woke up to 4" of snow, headed north to Denver and got out of it. Had a DOT freakout at the Loveland pass tunnel that took a half hour with a tape measure to fix, Had to love my Colorado pilot car peeps. they were the best.
