When I first heard about The Slab, I thought it was a piece of meat or something, but it's really a place in the Texas hill country where a river flows over a huge piece of granite (hence the name - slab) Lo and I piled the kids in the van and went on a road trip to check it out and I am happy to report, we had a blast. It's not run by anybody, it just sort of exists. And the kids played on the areas where the rock has been formed over thousands of years, by the forces of nature, into smooth water shoots and slides. My kids, wondrous new life on this planet and the ancient, weathered granite. Gave me pause.
