pie crusts??

Can you bake a gram cracker crust?? I want to make a pecan pie and a pumlin pie...any suggestions??? "Lucky"

Certainly, but I'm missing the point.  Why not make a pie with a pastry crust?

Graham Cracker crusts tend to be "sandy/pasty" not unlike the filling of a pumpkin pie.  IMNSHO, you'd get a better pie by providing the textural contrast in the standard crust or perhaps a shortbread crust.
