There are plenty of places in the US in which to tan topless. There's one at the Jersey Shore, there are a couple of them out on Fire Island. I've also done it in Key West, FL and Provincetown, MA - and I've heard of many others. Usually, it's a gay beach or a nude beach, but there are other ones, too. Not having children, I never frequent a family beach. So, as you can see, the topless tanning question is not about this one trip only.
