The missus and I spent several days poking around the deserts of California and SW Arizona. I've posted the 160+ images on my own web site, if you want, follow this link: http://www.sarracenia.com/galleria/g352.html" onclick="window.open(this.href);return false;
Mostly images of cacti, but a few other plants as well.
Don't be alarmed by the web site---it is a pseudo-art-museum that I drafted to house my photography. It pretends to be a snooty museum, but doesn't intend to fool.

Cheers
Barry
