This isn't it, is it? This's just a wolf spider. I'm looking for Nebraska-native spiders. Looks like the recluse is found in some parts of the state. They aren't native to California, but I've heard of some sightings around here, so it's not impossible to find a brown recluse in your area.
One thing to keep in mind about spiders--there's been a small epidemic going around from people dying after using public toilets in airplanes. In an autopsy, bite marks were discovered on the victims' rear end. There are deadly spiders that like to hide under toilet seats. Just so you know... I always check.
