Before I read the review I thought, "This sounds like Turner Park". Sure enough, it was.
I can see the dissenting opinion to some degrees personally. You play next to a road on I think 5-7 holes iirc? I know I've had my disc run over by a car on hole 16 or 17. I can't remember which one it is. Downhill, 650' hole. I overturned my disc and it sailed down the road all the way to be pin high in middle of the road. I was walking to get my disc when an oncoming car swerved to run over it.
The playground, while often not busy, has had errant shots fly over/near it from bad tree kicks on holes 1 and 3 I believe it is. Hole 4's blind shot over the hill I've often had discs roll into the park road there as well, which does get travel by cars, though admittedly not often. There are at least 3 long walks to the next tee on a few holes that I remember. They're not grueling long, but not great when the course is already so extremely hilly and long. Every time I played Turner when I lived there, I was exhausted after the round.
Now, as far as crossing fairways goes, I can't think of any holes that cross each other. Maybe a couple on the back 9 get close in certain positions if you have a bad shot that hyzers out?
All that being said, I really like a lot of the holes at Turner. It has some of my favorite holes I've ever played. I certainly wouldn't rate it a 2, but I think it's a stretch at 3.75 also. Maybe that's my bias because DFW has so many courses better than Turner, I just don't see reason to play it much, if at all. You're always in spitting distance from a better course that won't leave you as worn out as Turner will. Solid 3 though. Maybe 3.5.
