Fences? We don't need no stinking fences.

U.S. ends "virtual fence" project on Mexican border.  A real fence is too ugly and sends the wrong message.  A virtual one isn't so ugly because it can't be seen.  What kind of fence would be acceptable?  I have a hunch that the only one acceptable is the one that costs the most and is the least effective.  This is usual modus operandi of the government.
