Obstacles are dangerous, but I the biggest obstacle to watch for is the distracted driver riding near you.
I left the office Friday about 3:30 pm. The plan was to go do a little work about 30 miles east of Nashville, ride on to Crossville, camp, and head to the Hoot on Saturday moring. Traffic was already getting heavy as I headed out of town, so the "Spidey Senses" were on high.
As I progressed across town on the 440 Parkway I was almost taken out twice within one mile. In both cases I was driving alongside drivers on cell phones who pulled completely over into the space I was occupying without noticing I was there. I normally do everything I can to spend as little time alongside a cage as possible. But, in rush hour one has little choice, I escaped incident by pulling onto the nice wide shoulder. The first driver never saw me until I beeped the horn waved to her from the shoulder. Two incidents like this in a mile will get your heart pumping.
I started riding when I was very young, and defensive driving was drilled into my head from day one. I was intentionally riding so I had a "bailout area" and constantly scanning for motion that would indicate a driver pulling over on me. Thanks for the training, Dad.
When I got out of town I pulled over for minute. One thing I have learned from poker is that its never good to play when you are steamed. I think the same holds for riding.
In the immortal words of the Sgt from Hill Street Blues, "Hey, let's be careful out there."
