This book came out a long time ago. I read it when it first came out and it introduced me into the world of ghosts and and lore. I was 12 years old then in 1982 and even now when I pick it up to read....it still takes me back to the feeling...when I first picked it up and sent shivers down my spine...in a fun way of course. The stories and the drawings were perfect together. A great book. I have all 3 volumes now and I hope he comes out with a 4th one soon.Thanks Alvin and Stephen for scaring the pants off of me when I was 12.

All the elements of a great movie. What can I say, I love to study the elements of war, and I enjoy a good love story along the way. This movie was a great introduction to the role airplanes had in the first World War. Featuring the story of the Lafayette Escadrille, and the role Americans had in the early aerial engagements. The story also allows those who have little knowledge about early technology to understand that it was very rudimentary. (Using hammers to clear your machine gun comes to mind.) The soundtrack was very well done, and the needed animation(?) was excellent as well. I highly recommend this movie.

Great idea or so I thought. I fell for the marketing hype. This little gadget is nothing more than a time stamp. You plug it in and it reads the time stamp and shows you what was playing on the radio station that you pre-selected when you registered on the web. If you were listening to a different station, you have to look it up on their site, which defeats the purpose of this thing. You can already look up songs on the net without this gadget. In fact, you can do it better without the gadget, because, emarker's coverage is limited (No AM, jazz, classical, or music videos). Save your money!
