Teresa and I visited Archer City last weekend: her suggestion. I have recently gotten on a collecting jag and decided I would try to get a copy of every McMurtry book published, preferably first edition, preferably signed. There are 40 or 41 books (depends if you include Daughters of the Tejas, credited to Ophelia Ray, but ghostwritten by Larry McMurtry). I currently have 32 first editions, 17 of them signed, and one 2nd edition signed (Texasville, which I bought in Lincoln, Nebraska when McMurtry was speaking there and had it signed to me - the only one in my collection expressly signed for me).
Teresa was pretty sure we would see McMurtry, because she works with a woman who used to live in Archer City who said he was often at the Dairy Queen. Turns out that he now spends most of his time in Tuscon, and only occasionally returns to Archer City. When he does, he doesn't stay in his large house by the golf course (see picture) but instead stays at the Lonesome Dove Inn on Main Street, where we stayed, in the Terms of Endearment room. We did get to see the Golden Globe and Oscar he and Diana Ossana won for the screenplay for Brokeback Mountain. They sit on the mantle at the Lonseome Dove Inn.
The main attraction in Archer City is Booked Up!, McMurtry's famous bookstore. It is located in four buildings around the town square. In each, there are literally thousands of books (somewhere around 150,000 in total). T and I found it overwhelming to even take such collections on. We browsed for a few hours, but it was literally tiring. I think we wound up buying 7 or 8 books (including a Jospeh Heller first/first that was signed and a Review Copy of Issac Bashevis Singer's Lonely in America).

It was fun to see places that a McMurtry-phile like me would recognize. We found out the pool hall where Sam the Lion held court was gone, but the ruins of the old theatre were still there.
