This is a quick 2 stage multi near the Allen Stone Dam. I was out performing maintenance on another cache and decided this trail needed another cache along the way.
At stage 1 is a telephone pole with a plaque with two row of numbers on it. Top row has 7 letters and the bottom row has 4. Use these numbers to discover the final coordinates –
ABCDEFG
WXYZ
N XX Z(A+C).(X-B)DF
W (Y+E)(Y+A) X(W+C).GW(B+Z)
