I felt I just had to share this.  I was weeding a cactus garden I have 
the other day, and as I was tugging on various grasses and the like, I 
noticed a sheppards purse with seed pods.  So, doing the good thing, I 
took the seed pods and sowed the seeds in a part of our yard that I never 
have to worry about the weeds.
