The challenge, it's easy enough. Simply find 100 Geocaches within 30 consecutive days that are NOT traditional caches.
You may find traditional caches as well, but within those 30 days, you must have 100 non-traditional found/attended logs. These may include mystery, multi, CITO, event, Whereigo, whatever... The only exception is Benchmarks. They are nice but since they do not count toward your final GC numbers, they will not count toward your 100 non-traditional finds for this challenge.
The final cache terrain is a 1.5, and the container should be winter safe. The difficulty shouldn't be in finding the final, but in the challenge itself!
