Hi,
I live in Maryland just south of Hanover, PA. I get up to the Lancaster area several times a year. I would try PA #462 between the cities of York and Lancaster. It is the road that parallels #30 until you get on the other side of the city of Lancaster. There are Amish homes and businesses along that road as well as quilt and other Amish shops. I am sure the Lancaster County tourist bureau web site could give you more detailed information.
Let us know how it goes if you get up this way.
