I have one more question. I like to know why I'm doing what I do. So,
relative to what you said, Ray, does the copper kill the snail or otherwise
disable it? I thought it was used as a deterrent, something the creeps
wouldn't cross. Is that right, or is it something more?

Also, about laying the copper flashing: Frank was going to put down a 2"
border around the edges of the benches, and wrap the legs. Is that the
right way to go about it?

Thanks so much for all the info.
