Far too many March's in the title.!!!! Opened July 1961. Closed September 1991. This was the second fail of the day. The post hatch is wide open but I just couldn't get to it for all the brambles Having spent over half an hour and scratched off most of my skin I gave up. Shame as with the hatch open its going to be getting wet in there. Maybe someone will visit it with some gardening tools.
