Those who complete (compleat!) the Munros can record this fact and receive the magic number by writing in to The Clerk of The List (See here). Additionally, a list of current compleaters is published annually in the SMC Journal.
Bill Donaldson - 160
Carn Ghlusaidh - 16th October 1977
Not only was Bill wearing a tie, he was accompanied by a piper for his final Munro!
