This photo never ceases to blow my mind. Imagine, take a step forward and you're in Mexico. Take a step back and you're back in the U.S. Until I saw this photo I always thought that our government had marked/guarded our border much better than this.
A simple and effective border fence, as in reply 142, could be built in one year for less than it costs to keep illegal alien felons in prison per year. Cost is not the issue, a simple effective fence would save billions in unpaid hospital costs etc. The issue is political will. Our elites are on board for the "North American Union," and will never build a real fence.
