This past shabbat I read in more than 3 different parsha sheets that the reason Yitzchak was not allowed to leave Eretz Yisrael during the famine, was because he was born in Eretz Yisrael, and inherently had more holiness. In fact, Hashem told him to go to Grar of the Plishtim (Gaza) instead of leaving Eretz Yisrael...meaning Gaza is part of EY...but that's not my point at all.
Rather, temporarily leaving Israel, even for good reasons (like smachot, and work) is still a bad idea.
I left Israel on motzei shabbat on a business trip. We landed in JFK...it took 75 minutes for our luggage (business colleague and mine) to arrive. Took another 15 minutes to get the Carnet (document for transporting commercial tax free goods) signed by JFK customs officials. Did I mention it was snowing? Its been in the 70's in Israel the past 2 weeks, and I was caught a bit unprepared for the freezing weather. Transferred out luggage. Took train to terminal 9. RAN like crazy to get ticketed...got stuck in security (after all, with a name like Jameel)...panted my way up the escalator to the gate, and as we ran straight to the gate, the ticket person grinned and yelled at me - "SAFE...you made it" (with 1 minute to spare).
Got on the plane, door closed behind us...and then we were stuck on the plane for 4 hours without takeoff...because of the snow. Leaving 4 hours later, I was frozen. When we arrived in LA, our luggage apparently had other plans.
Just called AA lost luggage computerized interactive voice recognition system...and "my luggage has not yet been located...have a nice day."
I'm starving...and there's no Kosher restaurants here. Be back soon.
UPDATE: Baruch Hashem for Ralph's supermarket...and entenmann's donuts. That should keep me till I find some real food.
