There are two years listed on this plaque: first year listed is 19AB and second year is 19CD. The first line on the Smaller plaque says "Mayor". There is one year listed on this plaque: 19EF.
Your task is to find the two plaques at stage one and use the dates on them to solve the coordinates for Stage 2. The Stage 2 coordinates are: N 39 1(C-A).ED(D-B) W 094 5(E-B).(E-C)(D-B)(C-B)
