PJ Gallagher riding his Penny Farthing bike on the Clontarf Promenade Wall. When I asked him to do this, I expected him to say no, like a sane person would have. When he said yes, I realised I may be responsible for seriously injuring him or killing him, so the pressure was on to make sure I got the shot! Especially if it was mid-fall!
Two things to note,
#1; Penny Farthings are extremely difficult to ride as there is no "free wheeling" and the pedals are on the front wheel (the same wheel you steer with)
#2; The wall he is riding on is about 12 inches wide and there is a 20 foot drop on the other side!
