What comes next in the series: 3, 2, 1, 2, 1?
Well it's arguable if that is the right series, I suppose. Technically it's either 3, 1, 2, 1 or 3, 3A, 2, 1, 2, 1. The first is what you see and the second is what is actually the case.
The answer of course is 27.
It is a sequence I've got to know well.
Well it's easy if you live round here. They are the junctions you come to if you drive past Manchester Airport toward the M62 (or M67 if you like).
You come to J3, then the next is 3A (but you skip it; technically it's after J3 but you only come to J3A if you don't go off at J3 in which case you don't get to J2, you eventually finish up at J5 heading toward 6, if you know when to turn left), then J2 (which you don't see since you can't come off at it from an anticlockwise direction) and J1 are on the M56. Then you come to J2 and J1 on the M60 - and then you come to J27 on the M60 and start going down again. (Circular road, geddit?)
But it is a bit of a surprise when you're looking for J2 and you have to go 3, 1, 2 and it's the wrong one. Wha'appen? as you might say. Well it took me a while anyway.
And you come down off the Kingsway and want to go West and you can only go along the M56 although you can practically touch the M60 so then you come off at J2 and along the A560 and up the A5103 (I think) and that does take you on to the M60 at last but you've skipped 4 junctions.
And don't get me started on J18. Nightmare.
But I guess it does actually work. I thought Bristol was bad there you only get in the wrong lane, not the wrong damn motorway.
