Got my access pass today. Ranger was real nice about it.
Anyone wondering, I got a copy of "Notice of Award" from a local Soc Sec place(she was bitchier than anyone), took that to the Head Quarters in Flagstaff, said, "I'm here to get an Access Pass for disabled people", he asked if I had Doctor paperwork, I said, "No, but I do have my notice of award", showed him the 2 page paperwork and he was super nice about it. Directly from their website, a "Notice of Award" is the same as a Dr. written paper. Its in a PDF and not easy to find, but a "benefits letter" doesn't cut it. Has to be "Notice of Award". Hopefully that's understandable and maybe helps someone.
