Annie, I looked at the website. There is nothing on their calendar for the 16th. They have a store but sell pumpkins which they don't grow themselves.....no fields of pumpkins. Hay Craig, do you know anything about Mother Natures Farm in Gilbert? There are some animals but don't know how close you are allowed to get to them.
What about the Phoenix Zoo? Maybe cooler weather is here to stay til next spring. One could always throw (sketch) in a pumpkin in the background.
