I'll post some pictures when I'm staging it later (I'm miserable about taking pictures on-Playa).
For securing the pyramid, I have rope loops attached to the plywood roof. On the ground, I use 10" lag screws with a washer and two links of chain. In between, basic Home Depot ratchet straps. With the corner edges of the structure are reinforced with EMT pipe, that REALLY holds it down. I use 1" foam because I wanted to make a smaller package for transport. Having used 1-1/2" in the past on a hexayurt, I can say that it would be plenty strong for this use. 50% bigger package though. As for stability from the tarp, I'm very confident in the shear strength of the velcro. (I use it for "wrapping" around the corners, and last year, just taking it apart caused significant damage to the yurt) What I'm more worried about is the strength of the foil on the panels. The manufacturer doesn't pay any attention to the durability of the bond of foil-on-foam. I may resort to laying a strip of flashing metal down for reinforcement. (I don't want to get involved with nuts and bolts b/c I want flat panels for stacking.)
