Leave it near the abandoned house. Leave you mobile number clearly displayed. How many car thefts have you heard of? especially in that remote location.

Although a friend was telling me of an incident in Qatar in the 60's. He got his land rover stuck and had to abandon it (near Al-Khor) and when he returned the next morning the accesible wheeels / battery had been stolen..... so beware the nomad....
