Now I have one, thanks to my friend Heather, who is moving to an apartment and getting rid of a bunch of yard stuff.
I bought some tools and sawhorses from her too, and she threw in a load of firewood.
The car was a bit Joad-like on the way home. I tied the sawhorses to the roof rack with a dog leash, jump rope and some of that plastic stuff used to bind copier paper boxes.
No worries, except for the brief oops of the sawhorses hitting the top of the garage door when I tried to back in. But all's well.
