A supplement to the 2020 Vision series. An easy puzzle to solve first. You will need the coordinates of the 2020 Vision caches from March to December. Using the minutes part of the coordinates only average the values from March to December. Once the answer is found apply the corrections S+0.2637 and E-0.231 to get the final coordinates. These will take you just around the corner from the main road featuring the host of appropriate signs, as there are no suitable hiding places from which you can see the signs themselves. You are looking for a speed sign in a roadside garden. No need to stand on the road or any plants. You are looking for a brown painted screw top container. Be discreet as cars and pedestrians can appear from nowhere. Trust you have enjoyed the series.
