The hex hammock stands were used by my son's troop at the BSA Jamboree. The boy in the pic on the HH web site is my son's class mate at school, though they each belong to a separate local Scout troop.
Before going to the Jamboree the Scouts had a shake down camporee on the grounds of the state capitol. I posted a few pictures in my gallery.
note that in this shakedown camp out many of the tarps were installed incorrectly, they were supposed to be below the horizontal support piece.
I am not sure who the individuals were who built the stands. But if it would help I ought to be able to find out from the man who was the was my son's SL at the Jamboree who built the stands and put you in contact with them. His Jamboree SL built the troops Gateway but did not build the hammock stands.
They built 3 of them, each could support 12 hammocks. Not sure what they did with the stands. I know they sold off all the HH hammocks after the Jamboree was over. I got one of them, unfortunately I decided to late to get the one my son actually used and got one with some minor damage to the zipper and tarp. My son was already an experienced hammock camper and knew what to watch for to not damage the hammock.
Hope that helps some.
