 An unusual color - lovely view! 18/Dec/11 1:13 AM Yeah, it's a lake! No guesses. 18/Dec/11 1:15 AM It's a wonderful colour in a very rugged landscape. I'd love to know where this is. 18/Dec/11 2:55 AM 8.4**500000040060900800003050001070001030008000725000500900050046000600290070002030000 18/Dec/11 6:08 AM 9.0*****008400000690300000305090000009200080053070940070009100000080601000001094000003200 18/Dec/11 7:51 AM 1. UP to 282. Whether G7=1 or 6, C1=D3=1, UP to 303. Whether F3=2 or 7, A2=3, UP to 81. 18/Dec/11 9:17 AM 1. Unique possibilities to 28.2. (Chris's) Whether g7=6=e9,e1=5,f1=3;OR g7=1,g8=9,c8=3;c1=1 UP30.3. If e2=4=b8,b9=7=i8;the 17 rectangle at eh46 is unresolvable.So d2=4.UP81. Chris, I can't see why a2=3 after f3=7 in your step 3.Regards, Alfred. 18/Dec/11 11:32 AM Actually, I'd like to know where it is, too. I was flying from coast to coast in the US, and this was somewhere below. I'm guessing California. - Keyan 18/Dec/11 8:11 PM 8.4**// FXW(9) -9h31.
