I think I know the solution to this. The reason they were lost is-they had no idea how to say or describe to anyone where they were exactly-as all the hills are named in silly squiggle where an average word is worth 28 points at scrabble.Everything helps.
Had a recent rescue (December) up just North of Fan-Brycheiniog (I think there was the picture shown of it earlier in the thread) - blowing a hoolie into our faces as we approached the approximate location, then we saw their light, then heard their whistles, I replied with three blasts back regularly of a decent loud whistle. Stopped when we got close. They never heard a thing, just saw our lamps getting closer.
Perhaps name the hills something more sensible like-Hill 1, Hill 2 and so on.
to be honest-I think the porridge woggs are pushing boundaries and taking the piss with a few of theirs also.
All in all-I think there's actually a strong case for making their national languages Morse code with a dedicated list of standard abbreviations for their common used phrases. Wouldnt need to be too long of a list and-It would make it far easier to tell what exactly they are complaining about when they do speak.
