In California they held the boys and girls tournaments together during the season. They had different brackets and shared the mats. No extra cost there. Maybe a little time. They all practiced together with the same coach. The only difference was when it came to sectionals and state. The girls had their own and the boys had their own at different locations. Granted California is a big state with a lot of girls. They didn't have a girls California High School Sanctioned state tourney until 2011 I believe. But like the comment earlier, there was a road paved for them to get that done.
