I meant no offence - merely my observations.
It makes sense about the grant (I didn't know about that) and you are right that it was the old stone built hoses which were in ruin. I must say I thought these were much nicer houses than the modern pre-fabs however better the facilities. Pity they couldn't have renovated the old buildings?

We thought the same about the abandoned cars - we never saw a scrap yard on the island.

However the abandones houses, cars etc is something we never saw on Lweis, Orkney or Shetland - certainly to the same extent.
