Started this morning from the Space Age travel center, picked up an empty trailer from Walmart in Hermiston then headed south towards Caldwell ID.
About 260 miles later I arrived at Simplot, checked in and got loaded pretty quick. They also had a scale there, but I scaled again on a nearby cat scale to make sure.
I drove down to Twin Falls then us93 south from there. My route suggestions wanted me to go to Salt Lake City and I15 south then us89 which is almost 100 miles longer. I'm now parked at the Petro here in Wells.
