Do the "traditional" Ninjutsu arts still teach some of the more, uh, unusual skills that were supposedly learned by the ninja of old? Things like Meteorology, Building fortifications, spying/espianage skills, poison making, fighting from horseback, etc?
Or have these skills fallen by the wayside due to a lack of practicality?
