Dirt Farmer, if you get out this way give me a shout. Live about 30 miles from the grasslands. A lot of the Santa Fe trail is on private property, but north of Elkhart you'll find Middle Springs and Point of Rocks - the trail is in close proximity to these sites. Wilburton ponds in the grasslands has good tent camping, water and vault toilets. Located just a few miles from Point of Rocks and Middle Springs. I was through there last week and the Cimarron was flowing. About 50' wide at the low water crossing and foot peg deep. Not many opportunities like that for us Western Kansas folks. Also, north of Hugoton, Ks just west of 25 is Wagon Bed Springs and the supposed site that Jeremiah Johnson(?) was ambushed and killed by Indians. If you're so inclined, you can head on west into Colorado and hit Picture Canyon and Carizzo Creek. There's a lot of history in that area also. Please feel free to PM me if you're so inclined and I'll share contact information and get you further filled in on the area. Take Care.
