Not captured in these photos was all the fun we had with digging the holes for the tubes, and filling them with cement.  We had rented a power auger, and managed to catch a root (who would have thought that all those trees we removed would exact a revenge?).  Anyway, we managed to bury the auger right to the handles, and spent some 3 hours digging it out.  Then we managed to put the tube in the wrong spot, since our hole was so large.  Did not notice that till after it was filled with hardened cement though.  In the end, we rigged a hoist across a ladder, and pulled the tube from the ground and got it into position.
