Griff:
     One more quick note.  When I was a lot younger I used to work for a farmer hauling cord wood in the winter to ship out on tractor trailers.  We used old tractors with old trailers on them in the woods.  I once asked about seat belts and why they don't have them and was taught that your best protection was to bail out and get away quickly/w3tcompact/icons/frown.gif!
     When I first got my tractor I was pretending it was a bulldozer and quickly going back and forth to grade an area.  I soon discovered that the roll bar was at the proper hight to catch me by the fore head so I didn't get ejeceted/w3tcompact/icons/blush.gif.  My head had a lump on it the size of a baseball, I know always where my seatbelt.
