While driving home today in a drizzle rain just as I got to the 275 Interchange it began to pour to the point of not being able to see. I turned my wipers to high speed they came up and stopped. I was in the middle lane I could not see to continue forward or to pull off to the right. Finally I chanced going to the right which eventually put me on the shoulder and by the grace of God no traffic was coming to the right of me. I had to sit on the shoulder of the freeway for almost twenty minutes waiting for the rain to slow down or stop. Did I mention I still had 15 miles to travel before reaching my home.
