More mileage than there was under the last six presidents. Something is still better than nothing.
This fence is almost worthless. It does slow down the average illegal a little but that is about it. It does nothing to stop drug smuggling as they climb it like it is not even there. It is also easily cut with a torch. Sure it helps a little but this is not the wall that we need or were promised.
Bottom line is that unless somebody is physically sitting and watching that section of fence it does nothing. Even when somebody is sitting watching they climb it right in front of us.
Why don’t we tell these invaders there are no free anything on this side of the wall? Maybe they won’t come.
