Sanitation of campsites. There are alternatives to dumping dishwater and shower water in and around campsites. There are plastic holding tanks for excess "gray water" and "black" (sewage) water that you can dump at a camp dump site. If you ever notice a strange smell at your newly rented campsite, it may be that the previous users dumped gray water, "bummer". If needed you can pull your rig over to the dump site half way through your stay and dump black and gray water tanks. Try to leave campsites cleaner than you found them including pet leavings.
