Are you taking 69 down toward Yellowstone?
Ya, Google says its all downhill to L&C Caverns SP. I hope so.
Stopped at Boulder maybe 7:00pm, checked into the motel about 7:30 started to work on photos. Drank a Pepsi to stay awake, dunno what happened but it kept me awake until like 3am. Somewhat sleep-deprived today.
Anyways, the OZ Motel here in downtown Boulder, I give it two thumbs up.
