This is the bonus cache for our Waterside Eating Adventure Lab.
Often visitors to Nelson enjoy having a coffee and snack, brunch, lunch or dinner by the waterside and the Adventure Lab will take you to a variety of cafes/restaurants of this type. The bonus cache is not at the given coodinates and not at an eating place, but near an area that may have provided ingredients for your meal.
It is really at South 41 1A.ABC East 173 1C.DBE where the values of A,B,C, D and E can be found in the journals of the Adventure Lab.
Bring your own pen/cil and tweezers will help.
