Yes weight. It seems that the word Siskiyou is Indian for "trap all rain clouds". As we passed over the mountains we got several rain storms. Not a big deal normally, but with the large amount of dust we accumulated from the logging roads our car now has an odd mocha paste on it. This paste is really weighing down the car, along with all our other stuff and the gas mileage is suffering. We plan to wash when next convenient, but I am sure as soon as we do we will be stuck in some weird dust storm or road construction.
