This afternoon (June 27th) there was a traffic jam on I-84 just east of the Dalles. After being at a dead stop for about 30 to 40 minutes - where everyone enjoyed a little stretch break and time to get to know other travelers - the traffic started moving again. As we crept along the first thing that came into view was the smoke, followed by police cars, a few fire fighters, and a lot of scorched earth. There was a fire truck still putting out flames on the bank of the river as we passed by. Last to come into view was the actual cause of the fire - a truck that was pulling a trailer that some how caught on fire. The truck was parked on the shoulder mostly extinguished and all that was left of the trailer was the metal frame.
