The land to the north of the Gila River, in United States territory, was too mountainous. President Pierce instructed the American minister to Mexico, James Gadsden, to purchase as much territory in northern Mexico as possible.
A bollard is a short post designed to identify or segment a location, guide traffic or protect sensitive areas. It provides an effective visual barrier for vehicles and pedestrians and can offer significant impact protection where effective security is required.
Using boleadoras (or bolas) is called 'bolear', and what you catch is 'boleado'. I have seen boleadoras of two and three weights. The two weights model was generally used to play, but have seen in museums too. The indians and matreros (outlaws) used the two weights type to break the telegraph lines.
