Hey Greg...perhaps you could repost those photos of your cactus fenceline from a couple years back...if you don't mind!?!?!
photos of your cactus fenceline
Do any of them try to charge the dog or are they just too used to having one around they just don't care?
@ALDABRAMAN Hey Greg...thanks for posting! I am so envious of that cactus garden. And all Opuntia cochenillifera...you can't beat that! BADASS!
Where there's a will there's a way!
