Need a little advice

I need some advice from you all, today i went over and picked up a load of seed corn and beans on a dropdeck trailer, open sides, had beans in plastic pro boxes weighing 2500 lbs each, 2 per row, strapped down, corn in bags was all strapped down except for one small skid in the last row centered in the middle of the trailer, shrink wrapped well but not strapped down, only 25 bags so thought i'm only going max of 5 miles to home, never moved an inch and then an over zealous police officer motioned for me to pull over, i was stopped at a stop sign, thought no problems, all my paper work was in tact, recent safety on trailer and truck and not over weight at all, but he was having a bird about this one skid at the back, he fined me $390.00 for an "insecure load", i explained everything and long story short he said he could drop the fine but smiled and walked back to his car, he gave me some advice saying i could either pay the fine, plead guilty with an explanation or go to court, he marked my CVOR license down on the ticket and i can imagine it will effect my record plus maybe increase my insurance, basically he told me to plead guilty with an explanation and maybe it would get thrown out by the crown prosecutor but a friend also a police officer said just fight it and take it to court, right now i don't have time as its getting close to planting time. So whats your advice, plead guilty with an explanation is what i am leaning to and hope it gets tossed, just don't want it to mar my clean record, hope some guys from Canada or Ontario can give me some advice and thanks for any and all replies and sorry for the long rant, just ticks me off that this officer is so gung ho for something so minor, am i wrong.
