Trevi Fountain

I've never been to the Trevi Fountain. This most famous of Rome's outdoor fountains has a legend all its own. They say that if you stand with your back to the fountain and toss a coin into it you will return to Rome someday. I am not sure I will ever get to see the Trevi Fountain much less return to it. But I do know that I could replicate the sight and sound by putting large outdoor fountains in my own backyard! That I'd like to see.
