We called the number in the listing and spoke to Mark right away.  He texted me the street address of the place, which is 1123 N Lacy Dr, Waco, TX 76705.  When we arrived he greeted us, and even offered to back our trailer into our spot when I told him we were new RVers.  Mark was friendly and helpful, and maybe a bit of a comedian.  We felt very welcome.  Our site was roomy and entirely paved, with a BBQ grill and picnic table.  There were grassy areas separating us from the other campsites on either side of us.
