I'm sitting here completely brain dead and utterly exhausted. Spent 8 hours today driving by myself. Most of that was in foggy conditions with visibility less than 1/8th of a mile (or 0.2 km). I never thought that driving could be such a taxing activity but I am completely wiped out. Of course we are supposed to get snow tonight into tomorrow so that will be another joy of shoveling snow. O well, at least I don't have to be at work until monday so I should be able to get some rest before it is back to the grind.
