Lawsuits, lawyers, and personal responsibility . . . and homeowner's insurance
Yan, count me in the "what me worry?" crowd.
First, the likelihood of being sued seems to be on the ultra-miniscule side. All this yap about litigation and frivolous lawsuits is just evidence that some have fallen prey to the extremely exagerated tort reform party line (and we all know I shouldn't be dragging politics into this forum!).
Simply put, although there is always a chance of being sued, the likelihoood of a serious accident is small (count how many times your friends with whom you have hiked have suffered injuries which require more than a band-aid?), and being sued for it even smaller (was it your fault? have they sued you yet?).
Do you own a home? Guess what--you are insured! That means your insurance company gives you a free lawyer in addition to your insurance.
(Now might be a good time to check that homeowner's policy--that extra million of homeowner's costs you something like $150 and gives you lots of peace of mind.)
AND, if this is work-related, there might even be worker's compensation insurance available (with most states barring tort suits against co-workers).
If it is not your fault, you won't be liable! Do you have some faith in yourself? And if it is your fault, wouldn't you be happy to know that your insurance company will help your friend or co-worker pay for their medical bills and lost wages?
You could have your friends sign releases. That also might be a good thing to do before giving a friend a ride. Or serving a cook-out dinner--God knows the chicken might have botulism or the cole slaw may have gotten funky. I usually don't whip out the release before letting my friends in my car or my house.
On the rest assured side: In the thousands of cases I have ever read or read about, I have never heard of a single case where friends are hiking or camping and one sues another.
On the practical side: Hike and camp with people you know and like, and who you believe have some sense of what they are doing. Then relax, enjoy the outdoors, and hope for some northern lights. Leave the releases at home.
