Those are great pics. I have wanted to do the trail in Charon's Garden but the past two times I have been to the NWR they have had bad dust storms and I cut my stays short. Will do that hike eventually.
Have been to Mineral Wells SP a few times (mostly to fish) but do not like to camp there because of the crowds. Too close to DFW area. Seems like everyone and his brother is there on the weekends.
