Welp, considering I've had an infestation of brown recluse spiders in my townhome for the past few months, I can tell you almost w/ 100% certainty that that IS NOT a brown recluse spider.  He's too bulky for a BRS.  BRS have legs that protrude from the body at almost 90degrees upward, and have the first 3 pairs pointing forward, and the last pair toward the rear.  As FFMCobalt noted, they are also quite small!  I was reading an article from an arachnologist who refuted the complaints of BRS in the west.  They simply are not there, according to him.  I'll pull up a link if I can find it.
So, it IS NOT a brown recluse, and it's not a black widow.  From the looks of it, it's not a hobo spider either (don't think hobos are even around that region).  I think you're probably pretty safe, just sleep on your back instead of on your stomach, as spider bites on the face are rather unsightly 
  
Good luck.
[edit]Also, another peculiar thing about the BRS.  The BRS' I've had in my home are very, very territorial.  By that I mean that they stay in the same spot, pretty much always.  I've found many spiders, and simply opted against killing them to see what they'd do over time (was waiting for exterminator).  Everytime I checked on them, they were in the same spot, hardly even switching directions.  I could go into some other very freaky behavior that I've observed regarding the BRS, but, lets let Ameesh get some sleep, he's got some busy days at MS ahead!
