Tough Sudoku for 21/March/2007

Hi Everyone,

Super busy today, implementing total fluff:

*Horoscopes*

Yep, check to the right of the page & you'll see a link to todays (incredibly accurate) prediction.

Members can also now store their birthday and their horoscope will be automatically displayed.

Y wing style - Again - is a possible major key to unlock today's tough.
Blogged again, link in the usual place -
Upper right column, under Check out the Sudoku Blog.

In spite of the circumstantial evidence, I have no control over the puzzles...

The railway line in the front of the photo is used by the huge iron ore trains which can be over a mile long, if I'm correct, and sometimes have about 3 or 4 engines to pull them.

Easy one today - simple eliminations.

Anne - that is a really good photo!

Thanks Frank - I haven't seen you on here before.

17:59. actually grew tired of doing this puzzle. maybe its because i was up at 0647 hours PST.

Anne, is the black coloring of the hill/mountain in the background indicative of the iron ore they are mining? Interesting photo...

Rugged, indeed. A lovely, sunny day here. Enjoy your day/night, wherever you are.

Another beautiful picture ANNE ,Agree with Wilodene that it is very clear there were an iron mining in that area.Is still there till now.?

Nice photo

13:23; really nice pictures today Anne, thanks for sharing bits of Oz with us.

Anne, that is another really good photo of the rugged country in the fairly remote NW part of your huge and beautiful State.

Thanks, Anne, for this picture. It is fun to see real pictures of Australia!

Here's a solution to Tough March 21 that doesn't require any techniques more advanced than coloring.
I write g5=6 as 5g6; this saves all those = signs for making strong links (:>).

Ian - take a look at comment 170 on your page.
(*_^)

HalT, I have read it and intent to reply to you, it's just that I have a few things going on over here at the moment. I will post a reply on my page

Good afternoon to all! Good capture in the picture Anne, but da-n, I think I just missed the train!

Iron ore isn't mined anywhere near where this photo was taken but further inland and railed to the port near where this photo was taken. But there is iron ore in a lot of the rugged hills around the area.
My son flew up north on Monday to start work on the construction of a new iron ore mine out from Newman, and other than the camp for about 500, there is nothing within miles of them.

13:45 Hi to all. Thanks for the info Anne.

Anne - those trains are no joke when you get caught at a level crossing - it's good to have a book handy - they take so long to go past.

Able to finish without guesses.

Great photo Anne, you certainly are well travelled. One day we hope to get over to W.A. Just looking at your photo I can just feel the atmoshere..I may be wrong but I can just imagine the hot sun, clean air, occasional light breeze and hardly a soul for miles!

Hello Meg - it all depends on where you are. In Albany we get a lot of easterly winds during the summer which spoil it for the beachgoers. We definitely have the hot sun, although not as hot in Albany as further north and inland, and of course, we have the clean air. But no matter where you are, you will usually see someone around.

finished the puzzle to have a look at Annes,yet again marvellous picture..and the info abt is more interesting..

Hi every one
Interesting website and the photos as well. Although i'm new and first time 2 write a comment but i've been solving the puzzles 4 quite sometime. Nice photo Anne.

Anne you are popular tonight, great photo hope there are more comimg our way.

Thanks for your proof Justin!
With practice, the Y wing that you use in your proof, and Y wing style that I use in mine - can be viewed as being the same in difficulty - In my opinion, anyway.

Simple one today.
