We don't really "strew" anything, I can't really fathom doing that.
We do have free access to lots of games, from board, to cards, to computer and even made up kind. We also have free access to a large sellection of books, magazines, toys, crafts, tv/dvd and cd media. I make sure the children are allowed plenty of free time to explore the Library and bookstores when we go, so they can find different and interesting to them subjects. My kids love to explore. I don't feel the need to leave things laying around cluttering up more than the kids already do, just to "entice" them. My kids are well exposed and enticed with out me doing it.
