I pulled my boat out last night and was on the way home. I was going down the road about 40 mph when this elderly lady pulled out in front of me. I hit the brakes on my pickup and locked them up then In about a second I hear the tires on the boat trailer squealing. I had to make a controlled skid to the left, as soon as she hears all the noise she is like a deer in my headlights and freezes and stops. Now I am skidding directly at her, luckily it is two lanes wide with a turn lane and I was able to move over a couple of feet into the lane next to me. Truck stopped at lot faster than I would have thought it should about 6 inches from the side of her door. Then she just gases it and takes off leaving me sitting in two lanes boat starting to jack knife but in could shape still and me with fingers buried into the steering wheel. Talk about pucker factor , luckily no one hurt no damage and just a slight raise in blood pressure. I got home and noticed that one of the rear tie down straps came undone as I was drinking a beer to calm my nerves dont know if it happend because of the sudden stop or just me putting it on in the dark. Sure am glad I got a trailer with brakes. After this I am going to be checking them a little more regulary.
