Wet ie green 'stuff' is always available, especially grass clippings - most peeps just bag it up and put it out for the bin-men. These can be 'harvested' and added to your heap as required.
The only problem with other peoples grass clippings is you may not know if they have used "weed and feed" and they recommend that you don't use these clippings for compost for about five cuts afterwards, or so I remember reading somewhere (here???)
I actually like weeds in the lawn. Cow slips in particular, but even clover and self heal and of course daisies and buttercups.
