Woofie, I make a stab slit with a utility knife, then cut the rest of the way with scissors. I cut 3 sides, leaving one side (adjacent to the handle) intact. It's most often the side with the label. Cutting all the way around the corners allows it to stay open easily on it's own. After that, poke holes in the bottom. No screw on cap is used. The pouring spout is left open to air, rain, and snow. Easy peasy.
I'm going to win you over to this easy method eventually!
Relentless, arent I?
