To answer your question Rasec,
1. Saudi is frikkin HOT. Gas is about 45 US cents a gallon.
2. Life seems very subdued, people are much more calm, you almost never see people lose their temper. But be careful, that doesn't mean they are unaffected when insulted.
3. Flying is a mixed bag, depending on where you are and who you fly.
4. Violence in any form is rare. The state department has a page for deaths by country. If I remember correctly, most in Saudi are from traffic accidents followed by suicides.
5. Live in a compound!!
6. Be friendly. Keep your mouth shut until you consider how others will (or could) interpret what it is that you are saying.
... So take the job, be nice, and things will be just fine!
