Hi Keef,
Renters Insurance, interestingly, I only became aware of this after my sister spoke to the guy at Bermuda Dunes Aiport (see prev post).
He said that if I wanted to take an aircraft for a couple of hours it would be cheaper to take an instructor with me (40 bucks an hour on top of the $75 an hour for the aircraft) as the cost of the insurance would be in the region $250 (payable if I wanted to go solo)!!
And here I was thinking I might be able to do a spot of cheaper flying in California
