Desert Caballeros is Open for Business to Everyone. We saw the sign yesterday when Poppina and I visited the Cowgirl Up! exhibit, hung only a few days ago. I asked the docent on duty at the Museum what the sign meant, and when it appeared. She wasn't sure, but she and I agreed that this most magnificent cultural facility welcomed every visitor, and did not discriminate on the basis of age, race, creed, religion, gender, sexual orientation, body fat index, years of education, HDL levels, blue state or red ….. everyone is welcome here.
