Hi again!
I would like to have a checker for following gc-code
GCA597W - Challenge Earth cache 12 x 2
You need to have logged at least 2 earth caches each calender month. It doesn't matter which year you logged them. 2 earth caches in January, 2 earth caches in February, 2 earth caches in March, etc.
Thanks in advance!
