I got a chance one time to tour the locker room of the Buffalo Bills, way back when they were still on the verge of being good (not THIS century.) There was a lot of stuff there -- it looked like this Storage Manchester place I heard about, but more on that in a minute. The players left all kinds of stuff in their locker -- Doug Flutie, for example, had boxes of shoes still in his locker, and this was May.
I thought a couple of things about that.
First, I thought "Wonder if I could swipe a pair?" because, well, Doug Flutie's shoes. (This was before eBay. I just wanted them for me.)
(No, I've never had a psych eval. Why do you ask?)
Then I thought "I wonder why they leave them here?"
Now I know: it's because we don't have anything like the Safestore self-storage they have in places like Safestore storage lockers available in a variety of sizes, for short or long term, all available from a company that also sells packing stuff, too, so that Doug could've set up his shoes in a locker in the offseason, and had them kept warm and dry until he came back the next year.
In fact, the whole Bills organization could've shipped their stuff there - -maybe keeping it safe until they move to Canada - -because Safestore has commercial and consumer facilities. So their locker room didn't have to be all cluttered.
Besides which, had he kept his shoes in a Safestore storage facility, Doug wouldn't have had to risk ME stealing them. Speaking of which, now that there IS eBay... I wonder what the statute of limitations on shoe theft is?
