Giant House Spider 3
I used this shot to ID him.
If you look at his chest plate (sternum) you will distinctly see spots. The hobo spider does NOT have these spots.
Here is a good pdf for IDing your potential hobo spider: pep.wsu.edu/pdf/PLS116_1.pdf
of course if you are bitten, try to catch the bugger, and consult an actual arachnologist.
