Brilliant series! Large hammer was quite easy to find. Notes on the other two: We were unable to find wrench despite extensive searching. There are two stumps along the field line. One is surrounded by thorn bushes and the other is badly decomposing. This box may need to be retired. Also, for the Screwdriver, people under 5' tall should probably bring a stepstool to be able to get into the pole where the box is. When feeling around for the box, you may feel a plastic coated wire - give it a pull...
I particularly like Screwdriver for its clever placement...and that it probably required tools to plant it. :)

Thanks for planting...fun stamps that led us to explore a new area of St. Lawrence county.

clues are spot on!! Thanks, who would think of January letterboxing in SLC.

Hammer and screwdriver are good ones for winter, the wrench was good but harder as the cemetery wasn't plowed. Loved the cemetery, would never have know it was there, thanks for the plant.
