To qualify for this cache, you must find 3 different cache types in 2 different states in 1 day, hence the name 3, 2, 1. The 3 different cache types can be from any of the cache types available now or previous.
The different caches types are:
Traditional
Multicache
Mystery
Letterbox Hybrid
Wherigo
Virtual
Earthcache
Webcam Cache
Event
CITO Event
Mega Event
Project A.P.E. Cache
Groundspeak HQ
GPS Adventure Maze
The former/grandfathered cache types are:
Locationless
10 Years! Event
Again, you have to have found 3 types in 2 different states in the same day. It could possibly be the same types in both states, it culd be 3 sperarate types in both states or a mixture of some same and some different.
When I qualified for the challenge personally, I found 3 types in 3 states in the same day, which was the original intent of this cache, but to get the name to work better, I just went with 2 states. With this cache being in Indiana and very close to a second state (Kentucky) and with Illinios not being too far away either, this one should be easy to qualify for locally. You don't have to use Indiana (or Kentucky/Illinios) for any of your states, just giving an example to see how easy of a challenge this is.
Please state in your log how you qualify. You don't NEED to name the caches, but tell the 3 types and the 2 states and what the date was when you achieved the feat.
