Just what makes you think your property is reflective of the entire US/Mexico border? There are any number of deterrents that may be used to prevent incursion; an electric fence being one of them. The idea is; seal the border, prosecute employers who hire illegals, turn off the spigot of benefits to anyone who’s not a US citizen, and deport those found here illegally. Israel seems to be fairly effective with their border fence. Why can’t we be as successful? It’s a real security issue, ya know?
You live in Illinois.
Sort of unseemly to lecture Texans on what the terrain on the border with Mexico is like.
