When we had our excavator dig the holes for the additions we also had him pull one of the clothesline poles out of the ground. What we found was approximately a cubic yard of concrete on the end of each pole. It became a challange first to find someone who could actually tip the pole over and get it to stay laying down because it would just bounce back to a standing position and then to find someone with the determination to break the concrete from the poles. We ended up offering $50.00 to whoever succeded in getting the poles clean and the concrete picked up. Trevor was able to get the poles laying down but Nate was money hungry enough to work for the $50.00. Thanks Nate! The second set of poles we just cut at ground level and will be buried forever only to be found by the next owners and the challange will be theirs to conquer.
