I feel the same way about concrete. It would be nice but way too permanent for my liking. I like using shingles to get a road up and running quickly. Easy way to get a look at how things will fit and easy to change. Not the best though because they do move when walked on.
The ultimate material which I plan on using for final roads is what they call stone dust or crusher fines. It packs hard like concrete and is fairly cheap to purchase.
Hmmm, come to think of it. This stuff might be hard to come by and more expensive for you out in the sand land.
Glad to hear your ok and survived the storm.
