Depends on where they are. Inside - sure. Outside but in a well enclosed yard - not a problem. On the front lawn - not such a hot idea. In a public place - definitely a no-no.

Of course you CAN run around naked - but in most parts of the world you MAY not as it's illegal.
Unless you are a pedophile and/or a pervert, I don't see why you would want to see them naked....
i think you mean "i like so much better when your naked"
