So glad you are ok. Yes unfortunately you should now plan on posting no trespassing signs on the rest of your property lines. Too many idiots out there hunting don't understand the proper safety that it requires. It is people like these that give us hunters a bad reputation. I have hunted for years and passed up MANY shots, because I was not sure where the bullet would go if I missed.
We always shut the dogs up during rifle season just in case someone mistook them for a deer. Kept the horses closer to the house too. I can't believe the nerve of some people, my husband was hunting our bottomland and saw someone cross our fence, when he went to ask what they were doing, they told him they were hunting on their property and for him to leave.
Later that same week someone pulled into our drive ( 1/4 mile long) telling me they were hunting, after getting permission from the owner. I told them I was the owner and the only people hunting here would be me and my husband. Luckily for me the dogs had already let me know someone was coming up, and I just happened to be outside standing at the tailgate of the blazer with my 30-30 right beside me. These 2 old boys didn't even get a chance to pull their guns out of the truck. Needless to say they left.
Please be careful, and thank God you are safe.
