That's a shame. A snake like that will keep all other snakes away, ie copperheads, moccasins, even rattlers. I have about a 6 footer around my place that I leave be, he is the ONLY snake I ever see also.....
If they were not so hard on birds and their eggs( Domestic and wild) I would agree with you.
The only snake I will tolerate is a King snake, the other's end up dead.
good luck
