They are on their way by police escort, but...
There's a hold up in the Bronx,
Brooklyn's broken out in fights.
There's a traffic jam in Harlem
That's backed up to Jackson Heights.
There's a scout troup short a child,
Medvedev's due at Idlewild

Bob has a point about not taking a new bin on a trip, but I guess that's mostly a nice way to rationalize not getting them in time for your once in a lifetime trip. If the bins fulfill their advertising and work for you, you won't need a break in time, you could just "point and shoot" and you're on your way to seeing your first GREAT GREEN MACAW, BANDED GROUND-CUCKOO AND CHOCÓ VIREO!
I don't really know what the hold up is, and I really do hope you get your EDG before you leave, but if I had to hazard a guess, the earthquake in Japan might have pushed back delivery dates.
