For me - Learning

Reading. I generally have a fiction and a non-fiction going at all times.

Shooting - Qual'ed expert in every weapon system as an MP. My dad started me with my first rifle when I was nine and had me shooting 1/2" red beads at 50m with iron sights.

I've kept that up with an okay few arms.

MN-44 carbine,
Browning A-5 12
Luger (police issue)
S&W M&P 45compact/mil safety,
2 replica Rem New Army 44's,
ruger 10/22,
ruger Mk2,
Marlin 22 sa (the aforementioned first gun)

As Gunner is, I am a fan of the Vaquero (and Ruger in general), I owned a P94DC, 44 SuperBlackHawk, etc. but sold them to friends and family. My dad has one, so I don't need one. :)

Aside from reading and shooting, I love board games, and hate (but still play) 40k (IG, SM:DA, SoB), Paintball (really more of a memory, but I still own the equipment).

I also like to write (mainly poetry, short essays, and flash fiction)
