Any of them good?
waks,
I can vouch for the Nelson-Atkins, Liberty Memorial and Truman Library.
All three are worth the price of admission. The Liberty Memorial is the only World War I museum in the United States. Since they added the underground part, it is fabulous.
Here are some pictures:

The Liberty Memorial is in Kansas City, Missouri. It is the only World War I museum in the United States. The new museum space opened in December, 2006.

The Walk of Honor has engraved bricks. There is an area for World War I veterans as well as other for veterans of other wars.
Samuel K Hines (June 5, 1891 to June 2, 1966) served in the World War and this brick commerates his service and memory. He turned 26 in 1917, so he was a bit older than many of the soldiers and was promoted to corporal on October 19, 1918 (found out on October 31st !)
Grandpa's middle name was Kaiser ! I'm real sure not to many knew that fact during the war !

On June 28, 1914, Gavrilo Princip, a Bosnian Serb student, assassinated Archduke Franz Ferdinand, the heir to the Austro-Hungarian throne, in Sarajevo. This ignited the World War.
America joined the Allied side in 1917. Here is an excerpt from Samuel K. Hines's diary (of the Meuse-Argonne Offensive):
Sept.26 The Big Game started at 2 AM. Barrage started 5:56 A.M. went over the top. I & Lt. Hughes were with Reg. Hdg. & they would not let us go to Co. 12:30 PM Reg. Hdg. Moves forward 3:30 P.M. Lt. Hughes was (allowed) given permission to go back to Co. and take part of 3rd and 4th platoon who had lost the Co. with him.

Here is an excerpt from Samuel K. Hines's (my Grandfather) diary:
Nov.11 11th day 11th hour 11th month. Armistice took effect. The big guns fired up until almost the last minute at 11 O’clock. The church bells started & rang for 2 hours. American and French Flags hung most everywhere. Our Reg. Flag hung between the French from the up stairs window of the Marie.

Dec. 25, 1914. There was peace in no-man's land as an impromptu truce was held !

After World War I, poppies sprang from the earth and bloomed. Each poppy shown here (9,000 total) represents 1,000 casulties from the war.
