What do you think of trying to aid the problem of travel bugs that go nowhere by conferencing with the "Cache Across America" group? We could try to set up a series of travel bug caches that would be set up so that a cacher would know to advance the bug by going to a specific next cache, or by a reminder to log in and then find the next cache in line for the direction implied by the TB's goal.
Also, by doing this, we could, in advance pick certain caches that are big enough to hold a bug and easy enough to get some traffic, and make them mailboxes for the bugs.
