This Cache is placed to coincide with the Third Tuesday in Eldersburg (3TIE) event for February 2022 which will be on 2/22/22 - the day of 2's !
The Cache:
At the posted coordinates there is a collection of mailboxes. If you look carefully you will notice that the mailboxes are arranged in cases that are each supported by a post. Note how many cases of mailboxes there are.
The mailboxes are arranged in columns, and each mailbox has a number. Add up ALL the numbers in the LEFTMOST column for each case. Note these sums. Keep the sums separate. Don't add them together.
To continue to the second stage, it is necessary to enter the information noted above into a checker which will return the coordinates for the cache. Be careful to enter the information in the following manner: FIRST - enter the number of cases, THEN enter the left column sum for each case, for as many cases as there are. The numbers entered should be next to each other, without spaces. The number entered into the checker should be 5 digits long.
For example: if there are 3 cases, and the sums of first column mailbox numbers are 15, 8, 8. The number entered into the checker would be 31588.
You can validate your puzzle solution with certitude.
