I was just wondering if this has been an issue for anyone else. I have a lot of black rat snakes on my land and they where getting in thru my fly pen to my loft.....I had to redo all my fencing because they were even getting through chicken wire, not to mention the opening is three feet off the ground with NO ramp leading up to it. I'm still a bit worried about the cracks in the gate and at the bottom a few cracks were pen meets ground.
