During peach season Costco sells "I'm ripe" peaches. Margo helps me to boil the skins so I can peel the peaches. We end up tasting a slice from each peach. They are so good and at least two or three are absolutely wonderful. This crisp is so good that we all look forward to peach season. We even freeze enough slices to make one in the winter. It's good warm but even better at room temperature.
