Right on, Granny! The current "fence" is a joke - we need a wall, and if the Chinese could build one almost twice the length of what we need over mountains and valleys more than 2000 years ago, there is absolutely no reason we can't build a better one today! Additionally, we need to have that wall patrolled and guarded - I'd recommend building military bases on the border.
"The feds make the Border Patrol ride horseback to patrol that area, so that they don't disturb natural desert."
Ironically, that "pristine" desert is used as a dump and latrine by the illegals as they trespass through the area.
