I have walked past Wallenberg Park many times without paying it any attention. Its a small park with no play equipment, ball dimonds, soccer fields, or anything else of note. I have long assumed that such a boring little park would be named after a local figure that managed to raise enough money to get thier name on a park. In short, a park that is not worthy of any notice.
One day I stopped and actually read the plaque at the front of the park. I was shocked to read about what Wallenberg acomplished and was disapointed that I had never heard of him before.
To find the final location you will need to read that plaque and do the following math:
Add the last 3 digits of the year of Wallenburg's mission together. Then add that 2 digit number to the posted N co-ordinates.
Divide 3,900,000 by the number of people affected by Wallenburg's mission. Subtract the resulting number from the posted W co-ordinates.
The final is a micro container with no room for a pen, hanging inside of the park.
It looks like the plaque has been removed and inst being replaced quickly. A picture has been added to the gallery.
