Their entry is a CD, with a picture of some rocky outcrop pasted to the front, and not much else on the back.
either they have written 600Mb of info on the CD , or about 3 bytes of address on the back.
the second image below is how it arrived, in the post, no envelope or tape or anything..
excellent effort guys!.
thanks for the fun.
( now to remove the photo,and see if there is any secret info on this CD or not, maybe It is a listing of all their caches!,)
