In 1985, I bought 1.5 acres of old mobile home park to put my house on. After I put a barbed wire fence around the property line, I moved in about five feet and planted a perimeter of buckthorn trees/bushes. I got the buckthorn seedlings from all over the area, telling perfect strangers throughout Central Texas that, if they wanted to get rid of the buckthorn seedlings in their yard, I would do it for them.
Then, 10 feet in from the buckthorn, I planted an inner perimeter line of Texas red cedars eight feet apart all around the line. Didn't cost me a cent, as I just dug out seedlings under the larger cedars already in the yard and went from yard to yard offering to dig up all of their little cedars. The seedlings varied in height from six inches or so to two feet tall.
After they were all planted, I went out to the open range on Fort Hood after a major field exercise and policed up about 50 rolls of concertina wire. I unrolled the concertina wire over the seedlings and carefully monitored their growth over the next five years.
Now, the buckthorn is growing along the inside of the fenceline, backed up by some very nasty 20-foot tall red cedars, with their branches interlaced through growth.
Inside that cedar hedge, at a varying height of between two and five feet, is a coil of very sharp, very rusty concertina razor wire.
My late wife wanted bunkers and machine gun nests, but I had to draw the line somewhere. [smile]

RESISTOR
Swear allegiance to the flag, whatever flag they offer;
Never hint at what you really feel.
Teach the children quietly for, someday, sons and daughters
Will rise up and fight while we stood still.
