Em, isn't it summer down your way? Not sure what the difference is between Summer/Winter in your area but most of what you report as increased may be attributable to people being outside more/traveling more often in "good" weather and school vacation time.
It sad about the man, his wife, and his cattle. Every First Aid/CPR course I have taken (including the refresher courses) has told a story much like that. Usually it involves a dog and an old man, and his son/daughter , but the point they tried to make is you can't help others, if you need help yourself.
I admit I may neglect that point of self-preservation, if I saw only a loved one in distress. Seeing a loved one, and livestock all "down" in one area would peak my alertness, hopefully.
What exactly is "people falling into drains"? Drains is a (usually) indoor plumbing term in my area.
