There is cell phone reception at the top of the hill....
When we got to the Glamping tent the list of instructions said ... Turn off your phone there is no coverage... but in an emergency walk to the top of the hill... No emergency but we went for a walk ... over an electric fence .. up the hill avoiding the nasty prickly plants.. picking our way to avoid the spring coming out of the hill ... up the hill to the top.. oh another hill ... still no coverage... so down we came ... lucky we did not have to ring out ...
