Weed Whacker 3000! (http://www.sciencedaily.com/releases/2006/10/061012094305.htm)

I kinda like the weed control used in Phoenix. Water is scarce, so many people have rock gardens instead of lawns. To control weeds they use a blow torch a couple of times a year. :grin:

I always thought steam would be a wonderful way to kill weeds. Cook 'em!
