I've never mastered a 'flying' mount (I assume that's the scooting and leg over method...). I feel I should.
I was once approached by an old chap in town, as I extricated my Galaxy from a rack. "Is that your bike?" he asked. "yes" sez I. "Oh", he said, "but how do you...." and then he tailed off in confusion and embarrassment realising that he was about to say "get our leg over?" to a lady. "Like this!" I said, swung my leg over the saddle, and rode off.
I wondered afterwards, did he really think women were incapable of mounting like that? I was wearing trousers, after all...
