I recall being told or even actually reading an anecdote about, IIRC, a group of climbers from the continent being hosted by the SMC in Edinburgh and making mistaken assumptions about the seriousness of the ascent of Arthur's Seat (i.e. they thought it was a much bigger hill than it actually is). I believe the alleged timeframe for this entertaining incident would have been the late nineteenth or very early twentieth century.
I'm struggling to find any references to it now. Has anyone else come across this story before and could maybe point me to somewhere it is documented (SMC journal?) or at least written down as hearsay?
