My wife and I are members of the US based Evergreen Club which is similar to airbnb but for empty nesters. We have enjoyed meeting such a diverse group of people. We travel to learn about people and places. As retired teachers, we are able to amble about more slowly and savor experiences. Our best wildlife experience was on the Galapagos Islands. China and Egypt were great cultural and historical trips. We travel to learn; learning is a life long pursuit.
