This is a nice place. It's clean, on a quiet road, surrounded by cornfield and farmhouses. I think that's what the host means by "150 acres". The actual available space is a couple of acres.
A couple of low-tech improvements would help: a hand-drawn map showing what areas ARE available for strolling, walking dogs,etc., with corresponding site boundary markers; if the host lists the campsites individually, and allows site-specific reservations, then the sites should be marked onsite, and site-specific reservations should be honored. I don't see the need for that. Just clearly state in the description that it's 1st come 1st serve site selection. The campground comfortably fits 3 parties, as far as we could tell. 3 sites are roomy, and level enough without leveling jacks. The sites are right off the road, on either side of the driveway, and at the back of the driveway itself. If you have dogs, you'll be walking them along the road, which is fine. If you CAN walk other places, please make those clear with an onsite and/or online map.
