Son of Elmo

There used to be in our basement a spider so large that we named him--Elmo. He wasn't a pet, but we didn't kill him. I've heard tales of my son-in-law and his brother Pete setting Lakeside hurdles time getting out of the basement and refusing to go down there to do laundry for years. Yesterday we had the exterior treated for spiders, but we don't do anything on the inside. Maybe we should. From tippy toe to toe I'm guessing Son of Elmo is about 3 inches.
