Note
Baby's first national park! Arches, which neither Tom nor I had been to either. We did two very chill < 1 mi hikes, down Main Street and then around the Windows/Double Arch area. Very neat, would love to go back and do some longer hikes! Was our first time in the framed baby carrier. Sylvia seemed a happy camper and it was relatively comfy for carrying however much she weighs these days.
Then drove to Denver. I-70 reaches 11,100 ft at one point and it was pouring rain. Not super fun driving (chains destroy roads), but sure it's beautiful if you can see more than 50 ft.
