Driving down I85 to work today in the HOV lane. Conditions = overcast and misty with a slight layer on the road. Thats not an issue usually; however, my shield was getting misty and when I wiped it smeared like oil. At that very second I caught a whiff of diesel. I was doing 75 and I thought "what the hell" 5 seconds later it was like I was driving on an ice rink. I can't tell you all how I maintained control and slowed and stopped to the inside berm; I can't tell you how I didn't get splattered from another car; I can't tell you how I then managed to get the nerve up to get on the bike and cross 6 lines of high speed traffic during rush hour. What I can say is I am thanking God I'm alive. It took a while to get back on the highway. Drive safe!!
