One of the most amazing places I have ever seen in my short 22 years of life is Pompeii. I've been blessed enough to travel to 11 countries already (which sometimes seems like nothing when you think 184 to go) and some of which I've been to more than once. This past visit was my second trip to Italy. The first time I was in northern Italy in Milan and Venice. This trip I was everywhere. However, Pompeii was on the list to must see. Nothing was going to stop me. It's strange to see something so beautiful. Something that could have been and once was. To think what could have been but will never be. It's even stranger to think how these structures have stood the test of time and more than one volcano eruption.
Determine your own adventure. Mine is obviously including seeing the world.
