we recently tore down our old swing set and playground type thing in our backyard and my dad said i could make a pb field back there. So i was wondering how much it would cost to make a hyperball field and how i should do the bunkers and what a good layout would be. also my local field doesnt have a hyperball field so i dont know much about the bunkers other than they are made out of drainage pipe and i was wondering also how to keep the pipes from falling over. do i have to but concrete in the bottom or sumthin to keep them straight. thanks
