Comfortable winter reading, thanks to the Texas heat endured by the characters.
There is a lot of humour, which manages to not be mocking or demeaning. It is not an easy feat when your characters are illiterate drunks, and their very human weaknesses are often the source of the joke (in that regard, Lonesome Dove reminds of Steinbeck smaller novels).
It is also very tragic, but something about the rhythm (this is a very long book, close to a thousand pages) makes it a very pleasant trot towards a tranquil and ordinary tragedy.
(Also, I got to learn some more about USA geography)

One of my favorites. Folksy western wisdom (the best kind of wisdom) packaged in a genuinely brutal depiction of the frontier. Love all of these characters so much. As for the rest of the series, the prequels suck, but I very much enjoyed Streets of Laredo. Would love to see another TV adaptation of all the books.
You were right: Streets of Laredo was good! I really enjoyed the drifting ways of Famous Shoes.
