I think its a good idea to track the lesser known traits because with
enough data, we might find a correlation between some of these traits and
pumpkin weight. Here's an idea: why don't we make up some kind of sheet for
the weigh off sites to give to each entry to fill out. These sheets would
be filled out after the official weight recorded and would include the OTT
measurments, parentage, number of fruit on the plant at harvest, approx.
number of leaves, growing space, stem length, and seed color. Even the
smaller ones would count because then we'd have a better idea of what
percent of seeds from a pumpkin grow the giants. What other things could we
use? Is this a good idea?
