To make room for other caches, the original Tarantism cache was archived. Now it's back!
Tarantism (n.): an illness characterized by the sudden urge to dance.
If tarantism causes you to have a sudden urge to dance, then GEO-Tarantism must be what happens when you are the FTF and THEN have the sudden urge to dance!
If tarantism comes upon you when you find this cache, even if you are not the FTF, go for it anyway! This is a regular sized cache now. Should be a pretty easy find just off the dirt path.
This is one of my 10 real words that you will probably never use series.
