Quite. I always like to have a lookie at a map before I set off, so at least I am informed about the route/heading/places en route. People who blindly trust a SatNav are eejuts.
When I taught engineering at night school I always told students that they had to know the answer before using a calculator. They used to laugh at this but I used to point out that you first had to estimate the decimal place otherwise the calculator answer could be orders of magnitude out. This principle applies to all technology, it is useful for accuracy but you need to know what you are doing before starting.
[penelope] Around my neck of the woods it would be hard to find a house with a chimney, never mind one with a proper coal burning hearth an 'ob and a couple of hunting dogs to keep one's feet warm. A few decades ago oil burners were all the rage but the cost of fuel seems to have put those foul things to rest - even the use of the common wood burning heaters seem to be well and truly on the decline. After your comment (mine was meant to be light hearted) I did look at Google and my local paper's classified advertisements. Unfortunately my common sense and nous came to naught. Should I ever need a scuttleworth of coal I shall be trawling the local railway lines for inadvertent sullage. :)
[Dujon] Apologies, I didn't mean my comment to sound so brusque, but where on earth do you live, you poor coal-less thing?!?! Next point: I don't think you mean 'sullage', unless you're burning cowpats and horse dung...
No, penelope, I didn't. It was a slip of the brain or fingers. Please read the word as 'ullage'. On the coal question: Australia exports huge amounts of coal and uses various grades of coal in its power stations but I can quite honestly say that in my fifty-odd year sojourn in this country I have never seen coal being burned domestically. It sounds odd, but it's true, although it's impossible for me to say that it doesn't happen.
I am sad about Hershey's practices. I just found out that they source their cocoa from cacao farms that use slave labor. Children are sold to farmers, never paid, are beaten . . . Mars and Nestle are not great, either. However, they promised to stop these practices by 2020. Cadbury for you brits is fine, but Hershey's distributes it in the United States.
[Kaggers] I suppose this is why it's important to check that Incidentally, we're Britons, not 'brits', pfffft. (And Norwegians, Australians, and residents of just about every country in between those two.)
