Fishing with my son he asked me to back the trailer in to load the boat at the end of the day, no prob says I. Well after many tries and much laughter I realized the problem was I could not see the trailer in the mirrors until it was already trying to jackknife. After a few times of this I got out, lowered the tail gate so I could see the trailer and viola, looked like a pro. Entertainment for others and a little wounded pride for me but all in all. a good day. Learn to laugh, especially at yourself.
