A horse bucks as it jumps over smoke from a grenade during a practice session for members of the Dutch cavalry in Scheveningen, Netherlands, Monday, Sept. 16, 2013. About 80 mounted soldiers and police were rehearsing on a beach in the coastal resort of Scheveningen, outside The Hague, for ceremonies Tuesday marking the opening of parliament. The horses were exposed to smoke grenades, and harsh sounds to reduce their chances of being startled by any incidents during the ceremony. (AP Photo/Peter Dejong)
