Welcome to the Tool Shed!
This cache is not located at the listed coordinates, to find it you will need to do a little bit of exploration around the highest peaks in the USA. Not too difficult really, just use the tools you have available to find the missing links in the puzzle.
Here is a tool to help you find the answer to the puzzle.
N MN IA KS AZ . 0 WV TN W OK NC 0 TX. ID HI NH
This is a list of various state postal codes arranged in order such that if you find the highest elevation in the state listed and substitute the digit in the hundreds value for the state code, you will get the true coordinates of the cache. For example, the highest point in Utah is 13,528 feet, so you would replace the code UT with the number 5. The N and the W of course represent north and west longitude and latitude, a couple of zeros are in there because there are not enough states with a zero in the hundreds value, so leave those just as they are.
This is my first cache to place; it is located in my back yard, but you do not need to enter the yard to retrieve it. My neighbor knows so he should not give you any trouble, but he may want to talk a lot. Just be patient and know some day we may all be retired with a lot of time on our hands!
The container is like none I have seen before, it is about two feet long and six inches in diameter with a screw off lid, so fairly large travel bugs and trade items are ok. You can drive right to it and it is wheelchair accessible, it is ok to drive onto the grass, I do all the time to get to my garage, just stick to the west side of the grassy area and please don’t spin the tires! If you come by and the door is open, it is just me in there, tinkering with stuff. If you need help with the elevations, look at the hint!
Have fun, it really is an easy find!
