Summer Peach Blueberry Cobbler

Summer is in full swing and all the stores are full of fresh ripe peaches. So what a perfect time to make a classic treat. I made this for the first time last night as a treat for some Pixar interns i know who are anxious to find out if they get hired or not. I'm hoping its a sweet distraction. =)
