I'm on the road to Del Rio a lot with work. I need to see that cemetery the next trip down. I have been wanting to see the little museum in Ft. Clark but it is closed during the week.
Google Maps knows where it is, headed west you hang a left at the top of the hill leaving town and continue on that road past a big sheep pasture on your right. There used to be a sign on Hwy 90 but looks like they widened the highway.
