Bouldering Walls are responsible for many good things; increase in standards, more things to do on a rainy day, better international rankings (arguably), greater diversity of climbers, better problems, nicer coffee, cooler pants, loneliness (just me) – and many more including posterior elbow dislocations.
It could be argued that this is not a good thing but it does mean a great many more people are sent my way.
In fact I saw this one yesterday in a 13 year old girl. It has been reduced and was recovering well but, well, it should have been avoided. How? Teach falling practice falling.
