Maybe Zombie won't go so far as to fill in your card, but he still makes darn sure classic traditions die hard!
There seem to be a few more gaps in the pics you took now but the numbers you mention remain very healthy and the variety of the arrangements on show is very nice, as expected. There's even a choice of vases.
And there's nothing like a balloon to take things that little bit extra over the top.
As for the deliveries, you've nearly got that down to an art (what with semi-set load sizes, route planning, rest/rotation management) and it's not a little one-time rush-hour style chokepoint you spoke of that will make a three-decade run of improvements and refinements of methodology go to waste.
Heck, you're already planning more exact research on the factors implicated. Just remember, sometimes (as you've learnt elsewhere) it's really all down to the RNG!
