1. Being a range officer trying to keep people from shooting themselves, others, and sending bullets over the berm and into the nearby cattle pasture who call me a "Range Nazi". I've got stories, let me tell you...
2. People who think food prices, their deteriorating marriage status, and all other evils of society are caused by ethanol.
3. Cut, paste, and run postings without any substance or value added to the newly-created thread. You know the type, it's a quoted clipping from a news article somewhere, with a simple "Discuss" tacked onto the end. Nope. No discussion. If you have nothing of value to add besides a "Discuss" or "+1", then it really wasn't worth posting, IMHO.
4. Kalifornians who cannot figure out that there is life in the Free States beyond the Nevada border - been there, done that, sorry that it still sucks back there.
5. The NRA isn't doing enough for gun owners, and the shrill ranting of GOA somehow is a suitable alternative.
6. Trolls who log in with a new username and faked IP address after getting banned, thinking they can outsmart the admin staff. The clue bird doesn't roost there, it appears.
