Asked Ranger if I washed dishes in my sink then drained the gray water into bucket and used his drain if that was OK. His answer was "Anything" drained out of an RV is considered "black water...
Hmmm...maybe it was a different ranger, but I was told grey water was ok. My ranger was in Oregon..where was yours..?:h
The ranger at a COE park along the Arkansas river advised me to dump the grey water right on the ground. Not everyone thinks grey water is all that bad.....Dennis
