It is not possible to see all of anywhere, but I have travelled pretty extensively in Ireland, the UK, France, Germany, Netherlands, Belgium, Luxembourg, Austria, Switzerland, Spain, Portugal, Italy, Denmark, Cyprus, Israel, Egypt, South Africa and Lesotho, Singapore, Sri Lanka, China and Hong Kong, Thailand, Japan, Australia and New Zealand. In the US I have been to NY, MA, CT, IL, CA and HI. Have also driven across a good bit of Canada. I have a long list of other places I want to go.
There is a lot to see in the world, and the more cultures you see the more you understand what is means to be human.
