Use of explosives!
Always a good skill.
....and of course anything involving smoke, pork and beer
Hmmmm, let’s see:
1. Barbequeing / grilling
2. Horse riding and training
3. Martial arts
4. Reading - lots and lots of reading
5. Marksmanship (rifle, pistol, shotgun - and a 1919A4 if I ever get it put together)
6. Ammo reloading
7. The occasional fine cigar.
8. The occasional wee dram ‘o single malt Scotch
9. Beer brewing (not for a while, though). Still have all the gear.
10. Knives and tomahawks.
11. IT and network engineering expert.
12. SUV enthusiast. I heart my Avalanche.
Come to think of it, there aren’t hobbies - they’re avocations.
