Not sure if this location is accurate
Across the street from where this listing is located there is a community center, the Vashti Skiles (old Langtry schoolhouse), where camping is allowed in the yard. There is a hose with potable water attached to the building. In town, you can use the visitor center for restrooms, wifi, and very friendly staff. The museum there is free and is actually very interesting with a beautiful cactus garden and butterfly garden in the back.
