I have thought about hitting Culberson for years. Nobody seems to hit that area much.
I have spent a lot more time hunting culberson county than val verde or crockett counties. Result - two VV alterna and three crockett county alterna and NO culbersons. I also know of two other people who have logged some miles there and they have had similar luck.
I do like hunting in that county since it is REAL quiet, but frankly if you want to find alterna, there are better quite places to hunt, IMHO.
The only 2 Culberson alterna I know about are the one that Toby Hibbitts found while walking on private land and the other one is one that was claimed to be found at almost 8000ft on Guadalupe peak (in UTEP collection, I believe).
