One Hawaiian weed farmer is resorting to another sort of security system that is not quite as usual. He is allowing a bunch of cows, belonging to cattle rancher friends, to graze on the property, which is about 40 acres. The cows will clear the brush and increase visibility so it will be very hard for anyone to sneak onto the property to steal any amount of marijuana. Since cows are pretty peaceful creatures, he is putting up signs that say "wild bulls" because that sounds a lot scarier than a mama cow grazing on some grass.

Sativa heavy blends can make your mind spin faster than is helpful at bedtime, and some have reported that it actually gives them strange dreams.
