When pulling in to that lovely spot, whether it is in a fancy campground or boondocking, be aware that the folks who were there before you may not handle their grey/black waste disposal appropriately OR they may have had an accident. . .
The sewer hose is a weak point in any waste disposal system. I'm sure that every camper has a tale or two they can tell. But some folks do things that, if they thought about it, surely they wouldn't? Like the guy I saw lay his sewer hose on the picnic table before putting it away or the guy who laid his sewer hose on the grass to hose it out with water. Ugh!
Remember what came through that hose, folks. Do you want your kids or dog playing in that grass? Do you want to sit at that picnic table?
There are going to be many more people camping who have never done so before and have no idea of the appropriate way of "dumping" their waste and will have many more accidents. Take precautions!
