Hot Dang!!! Doesn't our guvermint know that "good fences makes good neighbors?" Even Isreal figured that out!!!
Parts of San Diego County has a "real" barrier as part of "Project Gatekeeper" but once you get into the high desert area, it ends and that's where they cross and the "coyote" smugglers leave their migrants to die. We've got water stations, we pay for billboards in Mexico but the "Latino community" still blames us for these deaths which happen each year to do exposure either freezing to death or dehydrating in the heat.
