We at EC are lucky, we get to play at the school on the football practice field. I know that at Lewisville they are allowed to play on the football field, but not allowed to prcatice there, they have to use a non athletic field down the street to practice on because the AD/ head football coach doesn't want them to tear up the field.
As for title IX it just states there must be equal opportunity for boys and girls so I don't think it comes into play here. If it said that all sports needed to be treated equally then Stone stadium would need to add about 75,000 seats.
