The airport manager asked me yesterday how I planned to
comply with the upcoming "two lock rule" to protect my 65hp
Champ from being stolen by a terrorist and destroying
Washington. I'm usually reasonably up to date on rule
changes, but I've been out of the loop for a while, and this
was a surprise. I'm not even sure if he was referring to a
state rule (NY) or federal.

At the DC-3 it's required you either be in a locked hangar or
have a prop lock on the plane. Dave Wartofsky just went out
and got a bunch of Kryptonite (generally regarded as the most
over-hyped and insecure bicycle lock in production) to allow
owners to comply with the rules.
