So, here she is for your viewing pleasure.....

I like the way the sun is shining through her legs

The last photo was taken in different light which shows off her color better. It's definitely a female garden spider, the males are much smaller, slimmer, and less colorful. The poor males also seem to have a rather shorter life span. Come mating time they focus so much on doing it that they don't take the time to eat and eventually starve to death (if she doesn't consume him first)! The females tend to find a nice spot and hang around for quite a while. There was one that strung a web between a couple of cypresses that I could see from my dining room. Every evening at sunset I could see her silhouetted between the trees. She was there for a few months, until we had a good storm that tore her web apart.
I think I've figured out that Spider Mom is some type of lynx spider. They are commonly found guarding egg sacs and do not make webs. She certainly looks like lynx spiders that I found photos of on the web, so I'm pretty comfortable in thinking that that is what she is.
