    Good experience opening a unit. Got a nice big clean unit with a brand new lock. I didn't have to wait long even in a line of 3 or 4 people and the man who was at front counter got me all my info and to the unit pretty fast. It costs about the same as any other place in town but they have climate controlled units which most of the other places don't. I highly recommend.

    We stopped in to basically check the place out and ended up renting a unit. If you ever need a storage unit where you can actually speak to a live human face to face, go say hello to John Norman the Store Manager. What a pleasure it was to do business with such a professional friendly person. If you ever need a unit, do yourself a big favor and go see John. He will do you right! Before we left he even walked us to the gate to make certain the code worked. Great to feel like you're important to a business again... Thanks John.. Appreciated it...
