We kept the first day short. We also failed to realize where the border with Mountain time is.
The objective was is a short jaunt up I15 with time left for a hike in the Cedar Breaks National Monument. The time-zone change meant we had an hour less than we'd originally thought.
The good news?
Hiking at 10,000′ requires patience. You can't walk far or fast. The timezone shift was a good thing.
Takeout from the Lighthouse Seafood was amazing. The dinners were huge, and we should have split one instead of ordering two. But it was soooo good we stuffed ourselves.
