I've had a post-it in front of me for quite a while now; thought it was time to actually post the locations on it here
Not in any particular order:
1: Mexico, for the Mayan and Aztec ruins, caves and cenotes!
2: India, so many places, but especially Mumbai's Elephanta Island with the temple caves!
3: Egypt, well, for pretty much all the stuff that Egypt is known for. The pyramids, the Nile, Abu Simbel, Karnak, the Valley of Kings, ruin diving in Alexandria, the list goes on and on forever!
4: Istanbul, really a city between the east and the west. Lots to see, including beautiful mosques, cisterns and palaces!
5: Budapest, Hungaria, for the very mysterious cave systems underneath the city! SOOOO much fun!
6: Cuba, vibrant city somewhat stuck in time. It just appeals to me
7: Anasazi Ruins, New Mexico, always wanted to go there and I'll more than likely will get my chance while being in Los Angeles next year
8: Greece, I just love this country. There is an incredible amount of history to see here and it's a great country to spend your summer holiday
9: Scotland, visiting castles and ruined abbeys!
I still have to think about number 10, maybe I'll come up with something eventually
