Triple Berry Crisp

I made this recipe for my son's Robotics Club banquet.  It went over very well. I think it was a success because most of the other desserts were store-bought. None of the other desserts were made with fruit, either. It is an easy dessert to make and turned out to be very tasty. I upped the sugar from 1/3 cup to 1/2 cup.
