Living Fence to keep out pigs and other critters..

[mangobingo]

There's a cactus hedge on 22nd in HPP, near Shower. It looks pretty solid although I don't know if it would withstand a pig. Do you think cacti would grow well in Mountain View, unknownjulie? I'd assumed they wouldn't but I haven't actually tried it.

Terracore - did it look like Acacia caven aka espino de Chile?
