A local coffee house gives away free used grinds. How should I used

I use them as mulch under my strawberries - they like it and the slugs
and potato bugs don't. I also use it in areas in my lawn where the dog's
have murdered the grass, and it seems to help decrease the eternal
spread of bare spots, and allowed others to fill in. Before I did this,
my lawn was a lunar landscape. They are not acid as you might expect,
and they are loaded with trace minerals, and break down pretty quickly,
so I just dump 'em, without paper filters, of course!
