[Q]: This thing is a major piece of junk. It doesn't stick to the wall like it claims. You have to stand to play with it (cause all the cool stuff is at the top), and the extension pieces constantly fall off. I actually screwed it to the wall, but that lasted a whole 10 minutes as it wouldn't stay screwed into the wall. Then the scenery kept falling. Save your money and buy the cool batmobile or something.
[A]: Negative

[Q]: This one doesn't really fall into the Western category, but it's full of hammering action, informative local California history, and mystic goings-on. Seacoast adventures, early Califronia ranching, great good-guys and really bad bad-guys, and mysterious appearances by silent, unknown characters fill this one to the brim! Best of all, L'Amour introduces in this story, for what I believe was the first time in his writings, the famous "portal to the other side," which really sets this story apart from almost all of his other works. Excellent yarn through and through. You won't forget it for a long time after you first read it!
[A]: Positive
