Oh nice, this is a long video. This time I was wearing my good headphones so I was much more aware of the rumbling sound below the lovely burbling sound of the engine. I also liked the subtle slow changes in the editing of the angle of view in the video. I would imagine that the lack of other traffic would add to the pleasure of the drive and I enjoy seeing the Japanese country side.
Thank you for your comment. The rumbling sound may have been due to a poor microphone placement. Next time I'll try driving the same road in the spring.
