HOLD ON, Chris.
Let's think about this a minute before contacting BCOP.
Letterboxing isn't as widely recognized like geocaching so doesn't have the "impact".
BTW Cachejunkies-Good question.
Do we as geocachers want to interfere with somebody else's enjoyment and bring down the rathe of the government? We will not change their minds on how caches are effected in BCOP so why open a can of worms that do not belong to us.
Just putting this out for discussion.

Qualiity. Not Quantity!
