Man,
You guys are on it. So that's a kids weekend for me but i may can work around it.
The best info I have on the place is this:
Very limited cell service.
The Bison and Elk range is very cool but it is a paved road that loops through the range. We went slow and saw a lot of each, actually drove through the bison herd as they were all over the road and on both sides when we got to them. Good close ups of both of these majestic creatures.
We explored a lot of roads. I did find that the numbering system was appropriate as referenced on the link Chris provided. Where the 300 roads were the most difficult. There were a few that I got down that I had to find places to turn around but I was by myself and pre KO2. I would have gone farther with some better tires and recovery options. Lots of mud on the roads/trails.
Turkey Bay had me a little confused at first but it was fun wheeling. There are some very tight trails there and some more open stuff with a huge rock garden. It is more small rocky with lost of fairly steep and off camber hills. We could probably spend a whole day exploring that place. It is covered in some more difficult places where one could have a crazy time in something less full bodied but there was plenty of stuff for the full bodies also. Also a nice campground area with bathrooms to have lunch.
MAPS:
The avenza maps worked great and I never felt like I was lost. They were super cheap and worth $$. I just randomly turned here and there and rode a lot of roads that looked like they ended up at the waters edge. At one point we were headed somewhere else and I saw a line of Jeeps turning down a road. I dropped a pin and came back the next day for a good little run.

This is what I used for Turkey Bay and the reason for confusion. There were so many trails at some intersections it was hard to tell where I was going. I did use a NFS map that I found online to follow my track and have a lot of the major intersections marked now with gps tracks. I would be a lot more confident in where i was going the next time around.

I also printed the MVUM. Luckily when I was there i did not find any closures.
I think that some of the places where you disperse camp are limited to number of campers and there are specific locations for larger groups but I need to look back to be sure.
