Heading to Yosemite next week..

If you want to slow filling up your gray water tank you can use the showers at Camp Curry or the housekeeping camp. I used to stay a week in the valley and my trailer had small tanks, 25 gallons each fresh, gray and black. Using Curry's showers allowed me to go the whole week without dumping. I was told they charge for showers but I never saw anyone there to collect. I would usually walk over about 5 or 6 pm.
