I live out in the country also and all of us out here had trouble for months. As soon as we replaced them they destroyed them. Threw mail all over the roads and fields. Sheriff would not do anything about it and neither would post office. Said we needed to catch it on video. Even though we saw it being done and gave them the license plate number and described the kids. We were told it was our word against theirs. So we set out at night with a camera and got it on video. They still wouldn't do anything. After 4 months and 5 mail boxes we changed tactics. We installed a steal post cemented into the ground, then totally covered at the base with dirt and grass. The top of the box was regulation size and looked plastic ...but....it was solid thick steal. It had the red flag on the side that you can raise up when you have mail to be picked up. The bottom was painted to look like aluminum the top portion was painted black with our address lettered on it. Then I set out for 2 nights with my camera and got it on video (for our use this time) and filmed it as they swung at it with a ball bat and broke their arm. Our mail box and all of our country neighbors mail boxes have been safe these last 4 years. True we were lucky that the kids didn't decide to do other damage after that but guess they figured it wasn't worth the risk fooling around with crazy people like us.
