I checked out the grand opening of what I believe was the first Sheetz in Michigan, last year near Metro Airport (DTW). It was interesting, but didn't measure up to the size and offerings of Buc-ee's. It was probably better than any of the Wawas I've been to (which isn't many). I do like that Wawa just north of MCO because it has reasonably priced gas for rental car refueling purposes.
For any Buckeyes out there, we are less than three months away from the opening of the first Ohio Buc-ee's, in Huber Heights, NE of Dayton. This thread expects a prompt report from the grand opening.
