I was in Grand Lake all weekend and traveled back over the pass on Monday (car). The road was mostly dry with occasional wet spots from runoff. It looks like they incurred a lot of pot holes and minor road damage over the winter. You will hit a number of 100-200 ft. gravel patches the last 10 miles before Grand Lake.
It was pretty damn cold in spots and windy at the top, but I would expect it this time of year.
I would've felt comfortable on a bike. I wish I could tag along, but I have some other activities planned that weekend. Damn.
BTW - 11 Moose sightings in 2 1/2 days was a little surprising.
