Got nearly 20 ounces, 566 grams for the more civilized.
Also some volunteer Jack-o-lantern pumpkins, I've had to pick them earlier than I wanted because a ground hog has devoured 6-7 pumpkins already.
It's also my first year. Trust me my hands were yellow and sticky by the time I was finished picking.
What I've read online says you should pick them when they start getting firmer and having a papery feel to them, and outsides start getting sticky from the resin.
