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.

David recalls: I'm one of, no doubt, many people whose first ever Munro was Ben Lomond (ie. the most southerly) with the last, many years later, being the most northerly. It was a splendid warm and sunny day and we had time to seriously linger on the summit. I'm the one standing (fourth from the right) in the white t-shirt.
