I consider this a success:

Before:

From 2009 07 14 Pumpkin Pollination

After:

From 2009 07 14 Pumpkin Pollination

If the pollination hadn’t “taken”, the bulb behind the flower would have yellowed and fallen off the vine by now. This was about 52 hours after the pollination, and the bulb has at least doubled in size.

I’ll keep you updated on the progress on our pumpkin!
