frost heaves

... and other road signs seen the past couple of days. Apparently frost heaves are problematic in Idaho, and I take them to mean that the roads are susceptible to cracks from frozen soil breaking through.

Then there were two exit signs listing the following town pairings:

Divide
Wisdom

and

Anaconda
Opportunity

I also saw a Halliburton property in northern Colorado, near the Wyoming border. I didn't stop, so it was hard to say if they were getting ready to relocate to Dubai too.
