Ron, You can feel free to pick me up on your way through Missouri...lol I know you'll travel I-70 and I'm just 16 miles off of it.
I saw some once as I was headed back from NYR (Sedalia,Colorado) with the youngsters a couple of years ago. I also got to see a muley buck feeding on the shoulder of the road too.
I couldn't look very long though driving a van load of kids with a trailer behind me loaded to the brim with camping stuff.Plus everyone was yelling "Eyes on the road!"...lol
Good luck and good hunting to all who are privileged enough to get to make the trip.
God bless,Mudd
