It's apparently a Sun thing. The letters are currently going out to the annual sites here at Rock Crusher advising that the meters will be going in. At the moment, it's only long term sites that will be metered. I'm a snowbird and my four month stay will not be metered at this time. There is aalso talk of metered electric on the way, which I expect will include my site.
In talking to the folks in the office, it's apparent the park has an enormous water bill they are trying to mitigate the cost of. There have been rate increases annually since Sun bought the park, generally at 2% or less a year.
