Don't think so. 16 y/o DGD is some kind of senior scout and a qualified cub leader, but as far as I know her summer is going to be taken up with Army Cadet camps.
I remember when DS, then 14, headed off to the jamboree in Denmark. Had a call to say "Don't worry but.........." A group had been sitting under a tractor - as you do - when DS sat up abruptly and whacked his head on the underside. Lots of blood and two stitches! No further problems but as his hair is now thinning the scar may reappear! Despite that he had a terrific time! Hope your GS has an excellent experience!
