the Spring (last semester of HS) and again during the Summer. I then helped him move in and then regularly visited him that first semester. We walked around their campus a lot.
That upper concourse near the close part of the horse shoe had a building along the sidewalk and it had a cafe and bookstore in it. The sidewalk actually continued around and back out of the stadium. There was no fence or way to stop people at all from walking in and out. Seriously never dawned on me that they may want to sell tickets and prevent people from coming in without paying as it just was not setup that way.
This has been 24 years so perhaps they've changed that but it felt very much like a HS or when I went to local DIII games...
