At the listed coordinates is Milang Post Office, complete with a plethora of post office boxes on three sides of the building. There is also a plaque (Milang and District Historical Society), that commemorates a particular service offered from here between the years ABCD and FGHJ. Use these numbers to calculate the final coordinates, which will take you to a spot where you possibly could have viewed this service all those years ago. Enjoy the views, park carefully and appropriately, and mind the busy road. I hope you enjoy it.
Final coordinates 35º 25.(C + J)(H - B)(J + J) 138º 57.(D - F)(G + A)(C - J), checksums 15 + 18.
