I remember looking at the “old style” website a couple of years ago, there was a printable leaflet in it that you could give to people when on a hill explaining SOTA.
When reading through it again yesterday I didn’t find it anymore.
I thought it was in the SOTA downloads section on Yahoo Groups but it isn’t. I too have some in the cupoboard left over from a rally stand. But I didn’t print them so I don’t have the file either.
