I was hoping to start a thread that we can all use to estimate distance using mildots in an urban area. For example how tall a fire hydrant is, ups truck height and length, typical size tires on a car, mailbox, licence plate, standard window, telephone pole, light pole, stop sign, red light height and width. I'm sure you get my drift. Maybe then expand it out to rural areas cattle, tractor, barn, etc. I would like to complied a list. So I'm hoping people will start carrying a tape measure with them and measure things through out the day.
