There is a place between 10th Street and 15th Street in Deerfield. Not sure of the name, it is on the west side of the street, just off of Dixie closer to 10th, the street runs parallel to Dixie.
Turn on the 15th/54th make your first left, about 3/4 mile on the left. The hydro scuba tanks, and fire extinguishers. Last time I was there I think it cost me $12.
