The challenge is to verify a found which is as far from the listing coordinates in km as the year has days on the log date.
The 30. June 2015 is the 181 day of the year. Now you have to prove, that you found a cache which ist between 180,5 (means >= 180,5) and 181,49 (means < 181,5) km away.
It would be kind, if you could create such a checker maybe if not green with the next possible log date (naxt farer Cache until 365/366 or at the end of the year starting from one km)
Thanks in advance
