Lost Skills?

 This picture )no further information) has just popped up on one of my Facebook suggested sites. Makes me think of my own Humperstein 'Grey Ladies' , a small unit of female hussars formed by Princess Aurora as bodyguard/intelligence gatherers. They have grey uniforms, hence the nickname. Perhaps they are modernising and moving onto cycles from horses. Mind you, from my experience of excersise on cycles momentum +swing could lead to trouble balancing.
