Oh lord, where to start?
0) My lovely wife (hi honey

)
1) Japanese sword arts (specifically, iaido)
2) Japanese swords in general (though I'm mostly interested in "user" type blades as opposed to "collector" type)--I do some koshiraeshsi (sword fittings making) occasionally.
3) My Shovelhead bobber (still in progress) and other scoots
4) Guitar and piano playing (love my Taylor 12-string)
5) Linux
6) Movies
7) "Golden Age" sci fi novels
8) Furniture making (bookshelves etc.)
My wife complains I have both the "collector's gene" and too many hobbies...I think she might be right.
