I think the question needs more definition.
This was Al's question. "What do you feel should be classified as the minimal regulation size for a board?"

I first need to know, what does regulation mean and who will it apply to? Are we talking in context of the MFCAL, a MFCA Guidebook, our local leagues or the hobby in general?

Before people get the wrong idea on these questions, I think is is important to remind everyone including myself of the purpose and mission of the MFCA.
Our Mission: Assisting the miniature football hobbyist by promoting miniature football, educating the public and providing an association which recognizes and supports the diverse coaches and leagues.

The MFCA is who? It's not the BOD. The BOD is in place to carry out what the membership wants and not the other way around. In order for the BOD to do anything, we need to know what peoples feeling are on certain subjects. At best and especially in the case of board size, the most the MFCA can do is make recommendations in a guidebook as to the preferred size field. Economics, room size, portability, personal preferences regarding surface type and so forth make it impossible for the MFCA to "regulate" anything beyond our own skills competitions.

I don't believe Al's question is going to effect anyones league or what fields they use. I think he is just trying to get an answer to what would be everyones preference for minimum field size for league play? Al, correct me if I am wrong on that assumption.

If that is the question than my answer would be 2x4 (except that I don't own a 2x4 yet). However, I see nothing wrong with anything down to the size of a Miggle Rose Bowl field. 500's are good for practice and arena.
