I think you can tell alot about a person from his favorite hobby.
Mine is scuba diving. I've always been interested in marine biology and ichthyology (the study of fish). As a diver with a bit of free time (and a bit of expendable cash), I've gotten to see some very interesting things underwater.
The highlights of my dive career have been :
-Seeing a school of baitfish devoured by marauding bonefish,
-Swimming through massive coral formations off the coast of Cozumel,
-Seeing a pair of state record sunfish guarding a nest at a no-fish quarry
-Finding the largest freshwater mussel I've ever seen (about 9 inches wide)
-Seeing the immense amount of stingrays that live right off shore of Panama City, FL.
