BTB:

This project we are doing takes alot of effort and responsibility but that is good. Doing this project i learned different things. Some things i learned are The U.S.–Mexico border has the highest number of both legal and illegal crossings of any land border in the world. Today, the U.S.-Mexico border covers 2000 miles, encompassing four U.S. and six Mexican states. But the area has changed quite a bit over the years.
