Anyone have an idea on how these would fair on the playa at BRC?

Thanks Brandon, I figured they would be a bit short. I cannot seem to find any decently lightweight or at least small packing genuine stakes to use out there. I'm coming in on two wheels instead of an RV so carrying 2ft long pieces of rebar is out of the question. The closest thing I have found are NRS blue screws, they come in 12 and 22". They are for sand and soil, don't know how they would fare screwing into the playa. What did you use?

I think these are a little small to hold up out there. the shape is right, but look for some about 12" for maximum tension when the dust storms kick up.
