If, at the end of all your spring cleaning, you’ve still got a “someday” pile—as in, “I might need this someday”—and nowhere to store it, call Denver’s Closetbox. The on-demand storage company will pick up those I-can’t-bear-to-part-with-it-forever treasures (or the things you just won’t need for a while, like skis and holiday decor) and house them in a secure storage facility in Denver or Longmont until that someday arrives. You pay $19 per month to keep up to four items out of sight but on hand when needed. When you want your gear back, hail Closetbox and your skis, bikes, or seasonal trinkets will be returned to your doorstep within 48 hours—probably less time than it’d take you to find them in your basement.
