Bad day. I decided to try it. 2 miles from first tunnel is a huge yellow warning sign stating anything ove 11ft 9 inches must exit over Bridge of the Gods and back across to the Interstate! The trucker atlas was wrong, the DOT website for height was Wrong. I even called the state Police. They said I was too close the limit to call.
So I canceled my 3 days at the Elk RV park in Trout Lake, was not able to meet up with my old work mate. To top it off the RV park charged me $60 cancellation fee!!
So here I am in Kennewick Washington and headed to Idaho. What a stressful day. I'm beat.
