Carpet Ball Tournaments/Leagues

The topic on 1-pitch tournaments got me to thinking. What variations have you folks seen as far as carpet ball leagues or tournaments?

I worked a tournament last weekend, where the plate and the carpet was a strike as long as it was a legal pitch height-wise. Started all batters on a 1-1 count with a courtesy foul. Pretty much straight up on the other rules. This was similar to another tournament I worked last fall.

There was a league in my area a couple of years ago that anything that hit the carpet was a strike, as long as it had the regulation minimum height. The maximum height was the sky (basically, NONE!). It was called the Okoboji Carpet League. All other rules applied as usual.

Just curious what all is out there. Thanks.
