Spent the last few days of May at the Cimarron National Grasslands in SW Kansas shooting prairie dogs. Drought and plague have taken their toll. I hadn't been there since 2005 and 2006. I was seeing a lot more dogs back then. Still saw a fair amount and got some shooting in, but their numbers seemed a lot fewer than during my last trip. They're public land dogs and are hunted hard. Many know to head for their holes when a truck slows down or pulls in. Was overestimating range a lot. Had the numbers worked out for size of a 9" dog in mils at 10X and 20X. I think a fair number of the dogs were pups and were not 9" tall. That and they don't always stand up!
