We have common wood spiders as big as saucers here. Most people don't know that because they just aren't lucky enough to be out that often to happen upon one. During the drought last year at home the ground was so bare (not from overgrazing, just little had grown, and the rest burned), we could spot the really big spiders from far away on the flats. Outside, I'll co-exist. Inside, it's war!
The DUmmy is probably one the few in his area to see that variety. Take a pic. Kill it. Go to work.
