On some days I just do a short post that primarily revolves around a favourite photo without much accompanying text.
As this is my 500th post, I thought it most appropriate to choose a favourite picture of the 500 series shinkansen.

It may not be technically the best picture ever due to the level of blurring on the train, but at least that helps to convey some of the speed it was travelling at.
