Question about Lebanon's football field

When did the metal bleachers become the visitors side? I went to the Lebanon/Radford game today and it was the first time I had been to a game at Lebanon since 1989. Back then the visitors side was the press box side. Any particular reason why they changed it?

I also thought it was interesting how almost all the home seats are on one side of the 50, but Blacksburg used to have the same deal for their visitors side before they built their new stadium earlier this decade.

It seems like in the last 10 years the visitor and home sides have changed hands a couple of times over there. I think around 05 was when it was set to the current seating arrangement.
