I'm sure there is a checker out there for this, but I can't find it.
The Central Oregon Geocaching Group adopted an icon challenge cache and we would like to add a checker to it to streamline the process. It is GC36RQW.
The requirements are simple:
Find at least one of six (6) different icons or cache types from the following list: Traditional cache, Unknown cache, Virtual cache, Earthcache, Multi-cache, Letterbox hybrid, any Event Cache, Webcam cache, Mega-event cache, Wherigo.
