Calif glider property tax fishing?

I'll give my tax man experiences and it may answer some questions /
devious plans to outwit the county:

+++ Sierra County sent me the fishing expedition letter and I ignored
it, they called up Truckee and asked old Les Seabold what an LS-6 was
worth. Les was a friend, so he told them 16K. I got a bill based on
that value. I then decided I would like to talk to them and called the
tax office. Errrr, that value isn't right, I only payed 6K for my LS-6
(factually true, but it was rolled up in a ball at the time) Too late,
you should have responded before our assed value was
assigned....................... I paid it.

+++ A few years later, got another letter asking about a Grob 103 I had
on lease-back at Truckee. This time I told them it was based at Minden,
NV. (somewhat true, as it left Truckee in the fall and could have been
stored at Minden) Nothing for about 6 months and then I get a letter
from Douglas County, Minden, NV. Thought I'd try ignoring them, bad
idea. They assigned a value and sent me my
tax........................... I paid it.
