That's a difficult question... there's quite a few I'd like to see. I suppose my first thought would be to say Germany. I once made a very quick passage through the country and, ever since then... I've regretted not having had the chance to look around.
Most of eastern europe as there something in the water over there.Just look at the amount of gorgeous ladies from there.
for sight seeing France to see where my grandad fought in the war.Japan for the culture.
Mexico (Yucatan), Japan, China, Tibet, Kenia/Tanzania (Serengeti & Masai Mara national parks), Thailand and Australia, but I'm going to the last one in feb, so I'll be able to scrap it from my list soon.
