I hope these ladies realize that the cows of the Spanish fighting breeds are actually more ferocious and dangerous than the bulls... The encierro in Pamplona has been for decades now dominated by drunks and American students (often one and the same thing) which led to its unofficial renaming as "the running of the idiots". I've never heard of a bull fatality in its course but plenty about human ones. Some quite gruesome pictures of the latter can be found at http://www.sanferminencierro.com/ .
