Those king snakes sound pretty awesome,I wish we had them where I live but unfortunately there are only Tigers and Copperheads here,it's a shame to kill them but the dangers are obvious,my little Am Staff loves wandering around the bush but I try to stop him in the summer.It does suck that we have to kill them because it's their land and all but yeah,better them than us,speaking of house spiders i've had a large huntsman on my loungeroom wall for the past 3 or 4 days and decided just to leave him there,they come inside if it's gonna rain and are harmless,he's still on my wall i'm looking at him right now,seems pretty happy where he is so i'll leave him or her there.
