Yes sir---I am. Just got home 45 min. ago---picked up my nephew this AM, and we drove about 40 min to a piece of BLM land along the Sacramento River. Probably walked about 3 miles---but I must qualify "stump"----down here in the lowlands, most stumps are from valley oaks, which rot slowly and stay hard----shooting one is usually the equivalent of burning a $10 bill. Instead, we find patches of grass in the occasional limited areas of rock free dirt in this volcanic landscape, and shoot at small branches or distinctive leaves, whatever. I usually glass the surrounding surface, to avoid shooting rocks---not always successful, but it does decrease the incidence of broken shaft suprises.
Sometimes we travel up higher, to the foothills or mountains to the east or west, where the conifers grow---there were really can shoot stumps.
Why do I do it? Fun, exercise, practice that simulates hunting situations, and any excuse to get out of the flatlands into the country in which I feel most comfortable.
Today, I could have legally hunted quail, squirrels, rabbits, even a pig if I had bought a tag for such, but we came home with only some trash that slobs had left and big grins.
