81 miles to Billings

I should just make it without another stop for gas. Good place to stay the night. They have a Comfort Inn next door to a Denny's restaurant. Good WiFi so I can load this stuff up to the internet.
Don't pass Billings without making a quick stop to see Pompei's Pillar. It's a few miles east on the Interstate and is a National Historic site. The Lewis and Clark expedition is recognized here with Clark's signature scratched into the stone. Don't try this yourself, it's against the law to do it now.
