In the course of ONE WEEK (1-7 DAYS), you must find caches that begin with each letter in your cache name (numbers & punctuation included -- hey, they're in your name too). You may NOT use the same cache twice if you have repeated letters in your name. You MUST find the same number of unique caches as there are characters in your name. All previous finds count.
To complete this challenge you will need to find a cache to spell out GEOCACHE using the first letter of the different cities in which you have found a cache.
If I am not mistaken a script extension has to be written for this challenge. But don't hold your breath because scriptwriters might not spend time on this because a challenge like this is not allowed anymore under the current guidelines.
It is not possible to make a checker because the system has not access to city names in the US
