Have to say, after resorting to another site a few times lately when I couldn't quite finish the puzzle (and scrupulously not sending in entries if I got undue help thus) I see why a contributor there referred to this forum in unflattering terms.
Not keen enough on train tracks to have ever finished one, but having slowly worked my way through this puzzle I found the special cells useful enough to decipher a route.
Had I started the puzzle earlier I might have called it too easy. As it is I've just finished in time to submit an entry.
So what do I find when I check this thread? There might be another route (I don't care) - and 28A is incorrect. Well, it's fine according to Chambers, which contains more Scottish words than most dictionaries, so I'll leave you to argue it out with the editors. I was pleased enough to get the final wrinkle to the clue.
I have to say that a forum where people boast that they solved a Listener puzzle on Friday when the Times doesn't come out until Saturday gets my back up - if only because I'm not a Murdoch fan and would never pay to get the puzzle online.
If you're that keen to get it, and then solve it in a night, what do you do with the rest of the week? It's bound to come across as rather smug and cliquey to the rest of us. I could be pretentious here and say that a Listener is like a fine wine, to be savoured at leisure, but obviously I wouldn't. That would show I was just as bourgeois and elitist as the rest of you!
