thanks! I actually suggested the airhorn some time ago on the forum. I came upon an Amtrak derailment last year and was one of only two who stopped :O( . I had just purchased four bulk packages of 16oz bottled water. Once the traffic was cleared, ambulances, Highway cruisers and Fire Units on scene, and people evacuated from the wreckage,WATER was on everybodies mind. I was one popular guy!
