Some of the new Challenges are giving me something to work on with OCNA.
The Ultimate Monthly Cacher - I've learned that I have not yet found an OCNA ONLY cache for 12 consecutive months. I currently have a 4 month streak going. This gives me a goal to work on over the next 8 months. I hope to complete this one in July 2016.
Variety Show Hider (Level 3 & 4) - So far, I only own 10 cache types. I've been wanting to get others out anyway, but these challenges will help encourage me to finally get them out.
Same with Variety Show Extravaganza, but the only type I've not found is an MP3 / Podcache.
