Going back to the popular San Isidro festival ... I could not buy tickets .. Everything was taken by the "abonos" .. season tickets .. Totally Spanish . I agree the tourists will be there at other times .. many of them .. but go to any magazine kiosk and you can buy the bullfighting magazines . It´s still immensely popular here in Madrid !
I support the bullfights because it´s a tradition of Spain . But I will support it and fight for it even if the Spanish government tryed to ban it ( unlikely ).
