This is the fence or WALL between USA and Mexico in Nogales. The left side in USA. It doesn't look so big in this photo but look at the cars on the left side. They are very close to the wall which is about 3 stories high. the gray to the left of the wall is concrete, it looks like steps due to the shadow lines of the wall but it is smooth and VERY steep. The fence to the left of the concrete looks little but is higher than my head. So sad that drugs have done this to this city. This is the OLD wall, the new wall is very deceiving and nice looking. I will post that too.
