I encountered very few people in the middle of this hike. Near the trailhead and turnaround point (about halfway between the Birch Creek and Nails Creek Units) there were a lot more people, but the trail is long enough in between to really filter out the less adventerous.
Though horses are allowed on the trail it looks like it gets far less equine traffic than McKinney Roughs. There's less stuff to keep an eye out on, but it still pays to pay attention.
The fishing along Yegua Creek at my turnaround point must be really good. I was quite shocked at the number of cars parked there, all of which seemed to have people with rods and reels coming and going.
The views on the trail are not great, but there's a good deal of mileage here and the elevation changes are not too tough. I wouldn't drive across Texas to hike this one, but I don't like THAT far away and I'm a sucker for wanting to map the remainder of the trail, so I'll be back.
