One of my favorite things we did was to go to the Blueberry Hill.  We were there less than an hour and picked 5 lbs. of blueberries.  The boys were so excited.  Wyatt kept screaming "Look, I found the biggest one."  and "Look at this bush, it has the biggest, juiciest berries ever.".
Travis did a great job picking until Daddy let him eat one. Then he kept saying, "I picked a blue one and put it in my mouth." 
First of all, who does Emmett look like?  Emmett had a good time too.  He tasted one berry from each bush of every size.  He came to the conclusion that the bigger berries that were bluest were the best.  The smaller berries and the ones with pink on them were very tart.   I wish I would have brought a notebook so we could have charted the experience and we could have counted it as a day of school. 
See, look how big.
After we finished we ordered Blueberry Ice Cream.
