how many cactuses (sp?) should I get do you think? I mean are we talking hundreds? I don't think it will matter what kind maybe a variety pack would be best. I wonder if this will even be legal? My neighbor has this kid and dog who always run into my backyard. These bees will be mean (cactus flowers anger up bee blood) so I know they will get stung, but that's gonna cost me some bees. Maybe I could do this in my basement...
