Some Spider

Living just outside our back door is a beautiful spider with red and white legs--we're pretty sure it's a marbled orb weaver. The spider only comes out of its corner when it's ready to wrap up some food, so it's a treat when we see it active.
 
I'd say the spider is about the size of a half dollar, the marbled sac like a jelly bean (not a tiny jelly-belly but a regular sized one!)
