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.
