Being as I have been here since day one, as were my parents. My brain is not tooooooo water logged............yet! But I do have gills to deal with said supposed great amounts of rain we have here. Better not tell those folks in Miami or Honolulu that they get 20 some odd inches of rain more than we do in Seattle.
I do run my dump truck at max all the time, but it is either empty, or fully loaded and then some!
80 hurts running empty in my rig. Now try 120 in the IHC with 6K on a 16K suspension!
