I jogged around on the trails at Slough Creek. Nice day. I saw a tortoise on the trail.

Note
Slough Creek update: I jogged the trails I hadn't been on and got GPS tracks. The tracks combined with the vegetation made it pretty easy to add the trail. The trail that heads east-west across the map doesn't get much use. I mapped it as an indistinct trail. My basic rule of thumb was if I was looking for the blazes to figure out where the trail went, rather than looking at the trail itself, then it was an indistinct trail. Where the trail crossed fields, I didn't draw it on the map.
I saw a few other features, like some ditches and a couple of hunter stands. I added those based on my memory and the lidar ground slope image.
Overall, the lidar-based vegetation is really good. It isn't perfect, but it is quite good.
And some non-Slough Creek notes....I figured out how to get the Microsoft building footprint data for Missouri. The geojson file is big. It didn't work through mapshaper.org. I tried using ogr2ogr in QGIS. That worked fine for small files (like Washington DC). I set the Missouri data to run overnight. When I woke up this morning QGIS had crashed at 4:22 a.m. and I got no results. I think it must be memory on my PC. So I read a bit online and decided to try mapshaper.org but using Firefox as my browser. And that worked!
I'm not really sure what I'll do with the building footprint data. It would be good for something like a big street O' map. It looks like the data is pretty good within Yellowstone, so I might make a couple of Yellowstone skiing maps.
