Last night there were 4 people who high beamed me when I was driving my 6420 around 11pm. I was going to one of our farms to haul 2 trailer/wagons back. So when I get out on the road. So I put on my seat belt road travel lights and drive around 12-13 Mp/h. After about 2 minutes of driving this guy sees me so he purposely uses his high beams because he thinks my high beams are on. You probably think I was mad and I was furious when this person did it. I did not really care then when I hitched up to my trailer I was heading back to the barn to store the trailer. Then trailer #2 I went to pick it up but this time I adjusted one of my work lights to flash into the other lane. (Im so mean ). So this time this guy has 4 lights of a light light green and these were so bright. I think they were LED's. So I flashed him good almost like a strobe. Then I get there again to get my trailer I am coming back and someone else had high beams on flashed them again. I am really mad at these people because there are signs on our road to respect slow moving vehicles.
