We learned to put up our own ger for the final excursion. Someone decided that we could figure it out on our own, so it took about two hours longer than it would if we knew what we were doing. It seems you rig up the lattice around the sids first. Then you hold up the taun, the center hole with the pillars and connect it to the lattice with poles/rafters. That part took the longest because we had to keep adjusting the taun and the lattice and the poles never all fit. Then we covered it with felt.
Apparently three serious Mongolians can do this in thirty minutes and students with clear direction can do it in thirty minutes too. I feel like I learned more trying to figure it out though.
