The things you see

Just spent 3 days at Cheynes Beach,WA, stayed at the only caravan park ( thoroughly recommend the place) and on Sunday the son and I went up the beach, before high tide peaked, to do some fishing, anyway we at some point started our way back, by this time the tide had almost peaked, leaving only one track width between the waters edge and the sand dunes, when we come upon a abandoned trailer with 3 three wheelers on board plus some other gear. We could see that further along, in the distance, there were a couple of vehicles and some adults and kids, so we drove around the trailer, as the waves receded and continued on towards them. As we got close the first vehicle facing us was a 1994 Holden commodore auto sedan and on the other side a bogged jackaroo who was trying to rescue this guy, his wife and a couple of kids.......enter us....one track wide...water on one side and sand dune on the other.
Can you PLEASE help us....we are sorta stuck. I said to them "you did well to get your car this far".....Can you help us they asked again.......They were using an old piece of rope as a snatch strap and NO other recovery gear, not even a shovel, and the rope kept snapping so that when I got there it was only 4 ft long.
Well the jakaroo unhitched and took off...when the waves receded we drove around and using a 6 metre snatch strap we towed him ( he was in reverse) for about 3 kilometres back to hard ground INCLUDING one creek crossing...He thanked me very much then leaving his car there, jumped into the jakaroo with his mate and they went back for the trailer , the wife and the kids and as far as I know, went on further up the beach to do some camping , fishing and motorbike riding.....go figure
