You got me thinking now JW. I have my granddaughter in my truck quite often, and I think that the car seat is properly fastened, but now I am going to make sure. If I was to wreck and she was hurt because of my negligence, I do not know how I could live with that guilt. Also, I have alot of crap rolling around the floorboard in the back seat where she sits (trailer hitch, handsaw, hammer, sledgehammers, etc) that I need to remove or fasten down.
One of my nephews was in a wreck about 10 years ago. He works for a surveyor and they had the heavy tripods (with the big steel spikes on the end of each leg) in the back of the S-10 Blazer they use for work. The tripods were laying in the back with the spikes facing the front. He ran off the road and into a creek bank at 60 mph. All those tripods flew forward and went through the back of both front seats, skewering him and his co-worker to the seats. They had several other injuries in addition to the spikes, but were unable to get out of the vehicle until help got there. Luckily the Blazer did not catch fire.
Now I have to use the same type of tripods for my job, and I am very careful which direction I place the spikes and how I lay them into the vehicle.
