On many nights if you wonder outside you can hear the howl of coyote. For me it is not just a sound to hear. On four different nights we have had one come up to our back patio. It never bothers anything (except my nerves). It just looks as though it is lost. I am not sure of how agressive they are by nature but thought it worth sharing with everyone. We have only seen the coyote late at night and once in the wee hours of the morning. I feel like the construction of the 3132 extension may have forced them from there home.
