I just watche this on satellite, do a search for it "Pig Bomb"..

the wild/feral hogs are getting to be a bigger and bigger problem. They migrate like nobody's business, are fertile at 7 months, and can have a litter every six months of up to 11 pigs each. They're night foragers for the most part in hot country, scaring them up during the day takes dogs that are trained for it.

After watching "Pig Bomb" there is no frickin way I'm hunting hogs without my 44 and a dog or two.

They are a PEST that have taken over areas of the south and southwest - if they're in Colorado at all, then they will STAY in colorado - "aerial" surveys that don't use nightvision/IR are useless in counting hogs - they don't move around during the day - any daytime aerial count is entirely conjecture and inherently inaccurate.
