For those of us fortunate.....if that's how you want to look at the stupid things....enough to hae pine trees...can ya take a machete or something and give them a good whack and come back a few days later and collect?....assuming spring or fall would be the better times for this. I know Ive seen sap before I ever wanted any, on injured pines, didn't know if that was a good way to injure them or not.
