( The A83 Tarbet to Campbeltown road, is actually called Rest and Be Thankful. Unfortunately the road is currently closed as a landslide plopped 100 tonnes of rocks and debris onto it. In fact it is the third time in recent years that the road has been forced to close by a landslide after similar incidents in 2007 and 2009. So I guess the name means – rest if you find yourself blocked by a landslide, and be thankful it didn’t land on your head.)
One of the main routes in Argyl, Scotland is called Rest And Be Thankful.
