These are sitting on 55 gallon drums filled with salt water. The tunnel frame is tied to 12 of these drums so that the tunnel does not fly away when hurricanes hit us. Hurricane Irene (Aug 29, 2011 BT (before tunnel)) did a lot of damage to our surrounding forest. UPDATE: Hurricane Sandy (Oct 30, 2012 TU (tunnel up)) roared through our yard and really shook the tunnel big time... very scary, did not sleep easliy, but those drums held firm and did not budge an inch.
