...you could poke your eye out.

We have all heard it before. Because I wear eyeglasses all of the time I considered them to be enough eye protection. A few days ago I was on the riding mower trying to fight west Texas weeds before the winds started blowing again when the mower ran out of gas. Since I was going into town later I decided to get more gas then instead of making a special trip. I ended up with more errands to run so it was getting dark when we returned home. I asked my son to drive the van around front while I put the gas in the mower and drove it to the front yard. It was getting dark quickly and I didn't see a low hanging branch. I'm sure you can guess the rest. No permanent damages but annoying.
