Sorry – just in case you thought you’d log onto the wrong site just then, I’ll explain… I’m experimenting to see if the words in the title of the post make a difference to the number of hits the site receives!  Obviously, anyone attracted to this post by the key words in this title will be a tad disappointed to find themselves on a site devoted to self-sufficiency and environmental issues!  So to those people – my apologies for bringing you here under false pretences.  Still, perhaps you’ll stay and…em..expand your horizons!  😉
