Well, I did a little research today and found out that the people we saw yesterday were not Amish, but Old Order Mennonites.  Similar in some ways, but very different in others.  The store we were at had electricity, and the aprons for sale had colors and patterns on them.  Hard for a Yankee to understand, but apparently, there are many sects, and even the Amish have many different beliefs.  So, instead of changing my post, I will acknowledge here that they were not Amish, but still very plain.
