I've had people call me rude and to shut my mouth when I tell them they shouldn't drink that water. saw it happen at a state park in Oregon and I just walked away. told my friend I think that guy is going to have the runs tomorrow. and since I never saw the guy again, I don't know for sure if he did or didn't have that problem. he had a motor home and it took a lot of water and we waited and waited for him to fill up his tank. I guess some guys just do not know what it means when it says non potable water. but he should have known what it means when the sign says DO NOT DRINK THIS WATER. some peoples kids!!
