While five pumpkins aren't really a lot, they're more than we've ever managed to grow before, so I'm counting this year's crop, above, as a huge success.
It got colder than forecast last night and the pumpkin vine got nipped, so the pumpkins were picked today. They should continue to ripen in the house, hopefully, and should all eventually turn the same color as the palest one. I've heard they store well, so I'm looking forward to enjoying pumpkin "something" from this crop over the next several months.
So, now we know it CAN be done—and next year, we will try again.
