N.T.
i rented hay bales for a party once. there is a feed store on main street just west of Mesa drive in Mesa. it was really cheap...but i can't remember the price. i had to put a deposit down too...but got it back after i returned them. it was super easy....just go down and tell them you want to rent hay bales and tell them how many...they load up your truck...and unload when you drop them back off.
good luck
