Ive lived there for years.....its great.
Jerusalem in the summertime, when the temp reads 90*F +, feels like 82* because the humidity is so low.
Also, if you did move to Israel you would discover a welcoming peoples who love Americans.
After the initial slight culture shock evaporates into the clearest bluest-purple skies you will ever see, you will begin to want to tour all over the Holy Land.
There is so much to see, and the feeling you get when you realize that you are possibly walking where Jesus walked.....is amazing.
And because the State of Israel is really quite small, you can visit so many places of biblical interest in a very short amount of time.
