FIRST OFF...slightly off topic...

I am having trouble with everyday weeds popping their dumb heads up. I wanted to know if anyone has any ideas for natural weed control. I have heard of a 20% vinegar solution mixed with salt, and dishwashing soap but do not know much about it. Does anyone have any pointers other than using round up. BTW the area is a relivley large area and isat my residence near my yards.
