Back in 1999, my brother and I decided we wanted to go out on our float tubes. His (now x) wife had just bought one of those cheap $40 2 person rafts. We went out from a pick-nick area on Soldier Creek, launched our tubes, and our wives climbed in to the raft with his 2 kids (I think they were 4 and 7 at the time). My wife was 7 months pregnant.
I THOUGHT my brother and I would go out and fish and our wives would paddle around near the shore (after all these 2 women were ADULTS with common sense, right?). About 15 minutes later I look up and they are paddling straight out toward the middle of the lake. I could see where the nice smooth glassy water turned to ripples from the wind that was coming over the hill behind the shoreline that we had launched from. I remember a feeling coming over me that there was trouble. I yelled for them to start paddling back, but the wind had already caught them (they couldn't hear me because of the wind anyway). I sat for a few minutes watching them be blown across the lake, trying to think of the best way to get to them as I was in my own float tube and I would probably never be able to get to them. Could I paddle back in to my truck and drive around to the other side of the lake to pick them up? Would they make it to the other side without capsizing? I could see them finally "wake up" and realize they were caught in the wind and start to try to paddle back, but it was about all they could do to stay in one spot against the wind. Just then some people in a ski boat came trolling by (stupid me I didn't ask for help), a guy from the pick-nick area came running down to the shore and yelled to the boat that they needed to go get "that guy and his wife and kids" that were in trouble (he had thought it was my brother and his wife and kids, instead of 2 women). So the boat people reeled in their poles shut down the trolling motor, fired up the big motor and roared off. When they got to our wives, they asked "are you OK? do you need a ride back?" my brothers wife said "no we're OK". At this time MY wife said "no we are not, we need help". So they got them and brought them back to safety.
This was a potentially fatal situation, that was prevented by some other GOOD people (the guy on the shore yelling to the people in the motorboat, and the people in the motorboat) who refused to sit by and let a bad situation get worse. I never got anybody's name to send them a thank you card or anything but I am grateful to this day for those people.
The "bad decision" for me was thinking that someone else (yea, MY wife too) had enough sense to think of the obvious risks and use their brain.
