Looks like the boys that are away up to the CIC tonight are not going to be experiencing a shiny extended, refurbished hut, but if a current thread on UKClimbing is correct, it is still an on-going building site up there
Have a look at these pics...

And one guy said that he found builders' rubbish all the way down the Alt Muillin

And a turd 5m from the door
Seems to me that the builders should be responsible for cleaning up after themselves and keeping their site compound to minimal size. Obviously the SMC also have a responsibilty here too.
As for the phantom crapper, that's just some thoughtless and selfish sod who should be kicked all the way down the hill. Hopefully when the toilet in the hut becomes functional this summer it will help prevent this. Well at least the folk staying at the hut will have the use of a loo.
