re: U.S. to Begin Border Wall Construction near Protesters Who Vow to Stop It

My biggest concern with this is not just federal government taking a "right of way" of sorts, but that the government is taking substantial amounts of land in some cases where logistics may make it preferable to place the border wall somewhere OTHER than the border

For instance, in the case of the National Butterfly Center "the wall will split the center’s property 1.2 miles from the border and cut off access to nearly 70% of its land"... That doesn't bode well for private property owners along the border.
