"I took this photo at Camp Baker in Florence, Oregon." —Renee Cabatic
I looked it up. Camp Baker is a Boy Scout camp. Here's a video, in case someone here wants to hear the local accents and see where those wheelbarrows live. My guess (I could be wrong) is that the wheelbarrows are to help kids get their gear to the campsites, and back out after they strike tents and whatnot. The dune descent contest seven minutes in is fun.
