Whatever the motivations, demand is increasing for inexpensive, yet adequate shelter that offers inexpensive protection from the elements. The yurt, in particular, is a popular choice these days. Not because it is superior to the tipi, but for its adaptability and compact mobility. Even a large yurt can fit snugly in the back of a small pickup. That's a real improvement on some of the water-filled or collapsed tents I've slept in or under.
Yurts also provide better intruder protection, against both humans and animals.
The supporting half of a yurt, or bottom half, consists of 2 to 6 sections called khanas. These lattice-like sections resemble stretchable, wooden baby gates. These sections, along with the door, are bolted together in an upright position and secured along the top edge with a steel cable that acts as a tension ring. The top half of the yurt frame consists of notched rafters fitted onto the cable at one end and bolted onto the top central hub with strange metal brackets affectionately called cling-ons for the function they preform. A smoke hole for a stove pipe can be cut in the center of the hub or out of a side wall.
