When I was Dustin's age, my mom and I would get together with other family members and go to Blueberry Hill to pick berries. I always loved it and I was SO excited when I got the chance to take Dustin to experience it for the first time! I know that him being three he couldn't care less, it's just another berry field to him, but it was so neat for me!
Dustin would pick all of the "green-berries" ...
... and then steal everyone else's blueberries!
