Are there any RadioShack stores left in the United States?

Excuse me, I was wondering if you could shed some light on a matter that's been puzzling me. With the rise of online retail and the seemingly endless expansion of big-box stores, I've been hearing rumors that RadioShack, that iconic electronics retailer, may have disappeared from the American landscape. But I'm holding out hope that perhaps some of their stores are still hanging on. So, my question is, are there indeed any RadioShack stores left in the United States, or have they all fallen by the wayside? I'd be grateful for any insight you might have on this topic.
