Thank-you, Brian. The map is a great resource.
On this same theme, I was recently refused the use of a dump station at the KOA in Spearfish, SD. The front desk person stated it was for registered guests only. She went on to say that a KOA somewhere had been forced clean up a situation where meth-lab users had dumped their toxic waste at a KOA dump station. She said that there would now be a national policy by KOA not to let non-guests use the dump stations. This was news to me, since I have done this in several KOA's around the country. Anyone else run into this "policy"? I suspect the lady was passing along another urban legend.
