Obviously, heinlein is just amazing. I've always, always loved Gulf. All you Zombies hit me a good one, as did Destination Moon and both the scout stories. Even By His Bootstraps, even though I'd recently re-read it in another collection, yet held my attention. I've also reread The Puppet Masters and Time For the Stars during my holiday, so a real good mix of new arrangements and old favourites. But this collection is great, some of the stranger stuff really makes one ponder.
