We just returned from Westside regional park in Bodega Bay, Ca, which is operated by Sonoma county parks department. We usually stay there at least 3-5 times a year. They have added something new since our last visit in May. As of 7/1/2013 even if you are a registered camper you must pay a $7.00 fee to use the dump station. This is on top of the $28.00 per night fee for dry camping. Credit or debit cards only to use the dump. When you swipe your card the lid to the dump is unlocked for sixteen minutes. When time is up an alarm sounds to let the park personnel know you have overstayed your allotted time. I don't know if the other Sonoma county parks are doing the same thing, but I would imagine they are. This is not intended to be a complaint, just for informational purposes for anyone else who might be headed that way.
