Mind you, they're both just peachy to bend, drill, or to
work with simple hand tools - luckily avoided here once
sharp edges are tamed.

Mirrors? We went on a garden tour and one guy had a tiny yard with
mirrors on the fences. It looked huge, great fun. He served tea and
cookies to the visitors.

I'm not interested in plants like Mo is, but the garden tours are fun.
One guy near the Presidio has a waterfall in his back yard, Lobos
Creek.

A micro-hydro project?

There are antistat sprays, which I think are mildly hygroscopic, for

Well, I mentioned earlier that dish soap can get films in the
megohm/square region.

Encourages hygene, too.
