If you love to solve puzzle caches, or you need a caching fix this winter, but don't want to brave the cold, then this might be something you are interested in. There are several caches that can be logged without ever leaving the warmth and comfort of your home.
Here are a couple of bookmark lists for this type of cache:
Haggis Hunter - Armchair Caches
Packman5 - Couch Caches
There are lots of duplicates between the two lists and some are not written in english (to add to the challenge).
This may not be for everyone, and some purists may consider it cheating, but I figured I'd post it here for anyone that might be interested.
