I was lucky to spend 6 months in India in 1990. When i went back the last time in 2005, was unbelievable how much the big cities has changed.
I also spent the summer of 1979 to 1982 in Alaska, living in a cabin in a remote spectacular valley, but never have been back. would be too sad.
When I bought a home where i live in wine country, the county had 130,000 people back in 1985. Now it has over 500,000 people. Sucks. I hate that apple processing plants in Washington bought all the apple processing plants in my area in 2000, and then shut them all down. So the apple orchards became vinyards and ruined my way of life. Better vinyards than track homes at least.
