Pie in a jar

Oh my stars and garters have you seen pie in a jar? Trina linked to the post at Our Best Bites that explains (in mouthwatering color) just how to make these darlings. I was wondering what would be the best way to make and freeze individual pies to take camping with us at Thanksgiving, and this is a perfect solution. Now I just have to find some jars. I'm thinking pecan and apple for sure -maybe some pumpkin pie too? Oh boy oh boy oh boy. This is going to be great.
