Just wanted to put my vote in for a Travel Bug destination query.
Not everyone would be using this and not all the time. Only useful when you are going a distance on a trip for flight, and only for dedicated TB interested cachers. This would not be used for normal queries but a sepecial query to be run ad hoc, not scheduled. This would go along way to moving some TB's.
Well, perhaps it will at least make it onto Groundspeak's "desired" list!
