Speaking from an administrative perspective, it is much easier hosting the SCHSL State Championship weekend at Memorial Stadium than Stone Stadium for many reasons.
The canteen is much more accessible and even allows the volunteer workers to catch some of the action on the field. The canteen has ample refrigerators and a productive ice machine (no hauling ice). It is easy to store overnight rather than having to break down the canteen set up we have at Stone and move in to a storage area and have to do it all over again on Saturday.
The fans split on both sides does have its' obvious advantages as well!
The locker rooms are bigger than those at Stone and easier to monitor for security sake.
I know that Stone provides an awesome atmosphere, but as far as convenience and manageability, Memorial more than suffices.
