When I was a kid, I used to play the chase game, on a dirt road behind my house, with a Blue Racer. I thought it was great fun. These days, I am wishing that the Black snakes I saw when I first moved in here would come back and catch all the mice that keep getting in my car and are too cagey to get trapped. I have never seen such intelligent mice, they have un-baited about six different types of trap and not gotten killed in the process. Have tried all the scent things that have been recommended too to no avail.
