Aranon - the pic from donya - huskerfan, shows you what screenings look like, copacted screenings - I just meant don't just put the stuff down, it HAS to be compacted using a power compacter - available for 30 bucks a day at your local tool rental.
Screenings is what they're called in Canada, I believe they're called crusher run in the USA, but don't quote me - essentially it 's the little bits and pieces that fall out the bottom of the crusher that makes 3/4" gravel from stone, the pieces are rice crispy sized right down to stone dust and compact extremely well with moisture.
