Leg Hair mistakenly removed from lazy river?? help!?

i went to hurricane harbor today(water park) and in the lazy river the floor is like a rough turf. while going through it numerously i had my left leg(side part) lay down on the turf. after i got out i noticed my hair was cut off. i am a boy so this isnt a good thing. for girls who want free waxings...go to huricane harbor!. how long will it take to grow back if my hair is half inch long. will it always be unevenm with the hair i have now. how should i hide it!?
