We thought this stretch of road just called out for caches so we finally decided we would just finally do it. There are lots of trees, all irrigated, but not so carefully maintained like they are closer to the cities, so they should be fairly muggle-free. All the caches are just off-road, can be accessed by a short walk from the shoulder of the road, or if you have a 4x4, you can drive right beside most of them on a sand track, and be able to stay away from the road altogether. There's a spot or two that you have to go back on road, but then can resume back through the trees. If you are staying on the road, please exercise caution and pull well off onto the shoulder of the road before stopping.
Too easy!
