In order to rent a locker for the semester or for a year, please visit the Service Center desk in the lobby of the Recreation Center. The Service Center accepts cash (bills no larger than $20), credit (Visa, Mastercard, Discover), Ram Cash, and check (with valid driver's license or state ID). A Campus Recreation membership must be maintained during the duration of the locker rental.
Terry, there are many storage unit places closer to the airport, but then of course you'd have to rent a car. DIA Self Storage, for example, is less than 10 miles away. You can google map Denver International Airport, then "search nearby" for "self storage units" if you think that's something you might want to do. http://www.coloradoselfstorage.com/
The storage lockers were a “pilot,” the kind of small test that city government frequently uses to test a new or controversial idea. The city offered up the lockers for individuals to use for months-long stretches. At the time, city officials warned that “misuse of the lockers, vandalism, or other unanticipated results,” could force them to cancel the project.
