I was just about to comment on the kerning, but Adam beat me to it.
There's some nightmare kerning (or lack thereof) in there. Wouldn't use it for body copy - but could be nice for headlines in print or other situations where you can customize the kerning.
Kerning seems to match the signs used in the parks. Isn't that on purpose? They are using it to service the NPS.
The website also reads (it was in caps, i'm not yelling): "A TYPEFACE DESIGNED TO MIMIC THE NATIONAL PARK SERVICE SIGNS THAT ARE CARVED USING A ROUTER BIT."
No, it doesn't. There's simply no kerning. On the signs themselves the kerning is more or less fine. Plus this typeface includes lowercase which is an addition (and so doesn't have the excuse that it's matching the signage), and it's pretty clear no attention was paid to kerning those pairs.
Those signs look pretty mechanically spaced out to me, too.
