I hate a dang pine tree. They're good for nothing but dropping pine cones, pine needles and sap all over everything. I had about 30 of them on my property, so for the past 3 weekends, my brother-in-law (who is a lot more limber than I) came over and helped me cut everyone of them down. Not sure what to do with them, as I've heard you can't burn them, because they pop too much. Suggestions?
