"My plane was in CA for a week's repair work and some
tax snoop saw it.  I got a bill from the state for some kind of property
tax.  I suggested that they shove it but they just keep sending bills.
Strange since I do not live and my company is not located in CA."

I just saw a news item today that the state of Maine is doing something similar.  If your airplane is in the state for more than 20 days you get a tax bill.  So Florida isn't the only state trying to stick it to aircraft owners.
