This should be a pretty easy TWO stage multi. At the posted coords you will find a very familiar sign with two digits on it. Once you complete the math, you will have the coords for the final.
Take the two numbers at posted coords and double them.....now subtract that number from 986 this will equal INS. Now take the same two digits and MULTIPLY it by 8 then ADD 17 to that new three digit number. This number will equal ANE
The final can be found at- N43 13.INS W71 32.ANE
