OK, you need to gather some data.
*** Be sure you are standing on the sidewalk when collecting data! ***
First, get the digits. Standing at the Southwest corner and on the sidewalk, check out the street sign post. If you read it from the street you will read the wrong side. The most awesome street name in Seattle is at the top of the street sign. Use the four digit number from the most awesome street name in Seattle as ABCD. The lower street sign has a 3 digit number, that is EFG.
Move south about 10-15 feet and look West towards the house. Be sure to admire the statuary and other decorations. You should be just past the tree with the pet food bowls attached. There is a 4 digit number on the wall past the gate, between waist and head high. Use those 4 digits as HIJK
From the back at the corner, move West about 15 feet from the pole with the most awesome street name in Seattle and look back at the 3 signs on the other pole. Use the 2 digit number on the lowest sign as LM.
Now the math to determine the characters.
! = A+H+K+G
@ = F+G+H+D
# = H+D+K+C
$ = E+H+J+M
% = H+I+J+L+M
^ = E+F+G
Substitute the characters into N 47 38.!@# W122 20.$%^
From the posted coordinates, you should be roughly 0.25 miles from the FINAL. If not, go find the error and correct it.
