Using the winch as a deal sweetener is good advice. I really don't think I need one, but after reading the Grizzly forums for the past few days, it seems like the winch is viewed as one of the more important add-ons - sort of like good glass is viewed on the 'Fire.

Looking at your pics, it doesn't seem like you would have a good place to hook up a winch. Could you drive a bar into the ground, or is it too frozen?
