read article on program to replace zinc fence w/ block walls. it mentioned lower security concern for JDF/JCF. Why does it lower their concern?

still can't see through a wall/fence. presume one can scale a wall as well as slide through a fence (not true?). easier for bad-mind to shoot concealed from between zinc sheets??

You can cast broken glass bottles into the top of a block wall for security. It works.

were in process of building a bamboo fence-about 7ft tall and the tops will be cut like an arrow-shape. Takes alot work to go cut bamboo down and bring it back and further cut it and put it up...But looks pretty cool-and bamboo lasts a long time..

Concrete block is best if you can do it, period. Render and paint it and its nice looking too. My godson walled his entire property in with a concrete wall. The rendering and painting part is going slower - as money allows but security-wise it is defnitely a deterrant - the thieves will go to the next yard that has an easier access.

Bamboo is tough and doesn't burn all that easily - it is also, as I hear, fairly resistant to duck ants.

I have friends who's yards are ringed with chain link. Again, expensive and can be cut through but not with four dogs barking with the intent to bite your head off.

As far as the glass thing, I've seen it done all over. The thing is though to make sure that the glass is such that it cannot hold water. If it holds water you have a Dengue breeding ground.

What I have been seeing a lot of is Bouganvilla as "perimeter" security. Pretty flowers hide nasty thorn that will juke you but good the minute you try to scale the wall.

I go with Armed guards in all corners with loaded ak47's. PERIOD !!!! block wall's, Zinc walls or barbed wire won't keep out the robber's !!!!
