Glue, NAW! We use Scotch Tape. Just kidding. Has anyone had any problem with the ground heaving? Due to frost? Here in NJ I have seen pipes pull apart and the ground move up and down by an inch or so due to the frost. I have seen PVC pipe pull right out of a box because of the frost. I might even get a picture on the board. ( I just need my kid to help with the digital camera. [Linked Image] )
