Guns, hand-loading and guitars.
I did salt water fish tanks for a while too but as mentioned they are costly and time consuming. Not like any of my other hobbies aren't...
Best in TX:
Real Ale
Revolver
Lakewood
No Label

If you're in DFW try to get a Martin House, they're coming up in the craft brew scene pretty quick.
