Ahh.  The forecast for today was 58 degree temp, cloudy, no chance of rain and wind from the South at 5-10 mph.  Started my ride at 12:30 pm knowing it would be the "heat of the day".  Actual weather; 45 degree temp, wind from the South at 10-15 mph.  At the 20 mile point of a 40 mile ride a heavy fog set in.  Visibility was less than a half mile.  Then it started to drizzle.  Because of the lousy weather I turned and headed for home hoping I was visible enough in the fog.  Only made 30 miles.  My point?  Why in the hell can't weather forecasters be a little more accurate.  How hard would it have been to predict FOG!  Of all the weather conditions fog is one I have the hardest time biking through.  As hard as it is to see bikers in normal weather, when riding in fog you are virtually invisible until the approaching vehicle is upon you.  So, to the weather folks I say a heart felt BITE ME!!  There, said and done.
