Premium Outlets are the best.
I go to them twice a year either at Dallas or Chicago.
But I think Ive been to that one too.
If you got CAA go to the foodcourt info booth and show your CAA and get discount booklet which gives you additional discounts on top of what is running in the store. If you dont have one you can borrow mine for your trip.
As for in the way go drop by Ellicottville. Nice town.
Here is the best route through that area. This was supposed to be one of my Saturn's Drive. THe roads through this are ais FAR from boring!
Rte.44. 60+ miles without a stop sign or traffic light, lined by trees and hardly any driveways
From Corsica then just head to Grove city.
