i was leaving the town dump today in my F550 landscape dump rattling down the bumpy back road as i hear, "HEY, SLOW DOWN!!." I immediately glanced down at my speedo and im doing 29mph in a 25. this has happened a few times now so i went back to tell her my speed and asked her to stop yelling at me. i told her its a very large truck and makes alot of noise becuase of all the bumps so it looks and sounds worse than it is. she was still upset and said her kids play out on this road. i told her anything under 30 is reasonable and asked how fast she drives on this road. can anyone guess??? she said well alot faster than that! just my rant, its been a while. then she thank'd me for coming back to tell her.
