A most excellent venue. Sorry we missed the trip this year but we still got our sand turns in down at GSDNP in CO.
For some of the questions:
* Yes, you just ski up the ridge of the dune. The sand is slow enough that you don't need skins and it would ruin them anyway.
* Sand is slower than snow (though the Bruneau dunes are significantly faster than the dunes in CO due to eons of weathering on the sand there while the sand in CO is a mere 65,000 years old). Accordingly, you have to find the steepest face and go straight down until your momentum overcomes the friction. Then you can make turns without bogging down. Be patient and don't force your turns if you don't have enough speed -- just like in deep, heavy powder.
* The angle of repose of sand is 34 to 37 degrees. I think at Bruneau it is at the lower end of that range because of the smaller, more rounded grains there.
* Some folks swear by Pledge. My theory is that a denser base material will be faster and Pledge helps a little on top of that. I use old Kazama Cornices and they fly. My wife's old Dynastar straight skis (Omesofts) are good too. Volants have a very dense base (same stuff as the Kazamas).
* Falling is a rather abrupt deceleration, but face plants don't really hurt all that much. Indeed not good for cameras.
* Wet sand is faster than dry sand.
*The Sleeping Bear Dune near TC, MI is about 200 feet taller than Bruneau or GSDNP but I don't think they allow skiing there. Anyway, it has canteloup-sized rocks in it. But there may be good sand skiing elsewhere on the east shore of Lake Michigan. There is also Sand Mountain in Utah but you have to share it with ATVs and some big dunes in Death Valley NP but there again, I believe the park service does not allow skiing. I am sure there are others but you want at least 200 vertical feet to make a decent run. Bruneau and GSDNP both are about 450.
SAND SKIING ROCKS!

GSDNP
I boiled my thermometer, and sure enough, this spot, which purported to be two thousand feet higher than the locality of the hotel, turned out to be nine thousand feet LOWER. Thus the fact was clearly demonstrated that, ABOVE A CERTAIN POINT, THE HIGHER A POINT SEEMS TO BE, THE LOWER IT ACTUALLY IS. Our ascent itself was a great achievement, but this contribution to science was an inconceivably greater matter.
