I have a local black bear on my property; we've observed him a few times. And he frequents the neighbors trash cans, or so we're told. But the bear is not what I worry about. Once while out walking by my creek, I was startled by a big tom turkey (not unusual to see turkey around here either). I went the other way because he was being sort of agressive. About an hour later when I came back to the same area, there was a big fresh complete turkey skeleton. What critters in southern Oregon eat whole grown male turkeys and leave only the skeleton intact, without making a sound? Hmmm.... That means there was a real big kitty somewhere watching me and Mr. Turkey earlier.....
Now I always carry a Ruger 357 Magnum when I'm out there by myself. Simple but effective and versatile, and I don't go broke when I plink w/ 38 SP. I keep the first 2 chambers filled w/ snakeshot, which has come in handy around the rattlesnakes.
Re: warfarin: actually rl71459, warfarin or Coumadin is a very common drug besides being rat poison. We use it all the time for patients with atrial fibrillation or artificial heart valves who are at risk for developing blood clots that could go to their brains and cause strokes. It's sometimes fun to see the look on patient's faces who don't know they are actually taking a "rat poison pill" daily.

P.S. Can you Canadians still buy ammo?! I mean, stores have been sold out around here for months, and it's getting real old!
