Points of interest around Ft. Riley? You must be joking...
Having been stationed there myself and done a Change of Command in February it can be bitterly cold and windy at that time of year.
From KC to Riley you have Ft Leavenworth and old Historical Post and still in use, Topeka has a nice Railrod museum, Manhatten is home for the Kansas Jayhawks Univ of Kansas, Riley has a great museum as well as several old military quarters on main post that are huanted, 1Lt George S Patton lived there, Captatin George Marshall, Lt Col George Custer, enjoy things in the area but the best part is the grandchild.
You might want to go here http://www.riley.army.mil/ to see some of the things in the area http://www.riley.army.mil/AreaInfo/ and on the post
Check weather conditions right before your trip. In February, it can literally be anywhere from below freezing and snow to a nice 50-ish. A longtime Kansas farmer once described February as "the snow month".
The drive from the KC airport to Manhattan is an easy 2-hours. There are also good shuttle services if you don't need a rental car while at Ft. Riley. I-70 is an excellent freeway that runs right next to Ft. Riley.
The Eisenhower museum is in Salina about 30 minutes away and is highly recommended. However, it is a campus with multiple buildings so make sure the weather is accomodating. Manhattan is the home of K-State University and there are a few things to do around the campus. Nothing special though. The area is know as the Flint Hills. Believe it or not, it's pretty. Rolling hills, native grasses, scenic views. There is a scenic drive between Ft. Riley and Manhattan off I-70. Watch for signs on I-70 to direct you to the correct exit.
Good luck.
Well, I'm on the faculty at K-State (the other major 'industry' near Ft. Riley).
Unless it's the day before, I wouldn't hazard a guess about road conditions
in Kansas in February. You could have anything from dry roads, sunny skies
and highs in the 60's or 70's, to snow-packed icy roads with snow and highs in the single digits or rain and highs in the 40's.
For sight-seeing, Ft. Riley itself is scenic (believe it or not), and has a museum to that military moron George Custer, as well as the original Kansas Territorial Capitol. Nearby, there is the Konza Prairie, one of the last stands of tall-grass prairie, jointly run by K-State and the Nature Conservancy, which
has some very nice hiking trails (and slightly further afield the Z-Bar Ranch, another tall-grass preserve). You know about the Eisenhower Museum in Abilene. Abiliene also has a few notable mansions--one built by a 'patent medicine' (aka 'snake oil') magnate, which is well preserved, and the only restaraunt in KS outside the KC suburbs or Wichita to get written up in guidebooks, the Brookville Hotel (serving the same family-style chicken dinners made famous when the restaraunt was in the actual Brookville Hotel in a tiny town south of I-70 about an hour west of Abilene).
There are a few architecturally notable courthouses fairly nearby (Chase County, being the most famous).
The state capitol in Topeka (a little over an hour east of Ft. Riley) is worth
touring, as it has the set of John Howard Curry murals with the famous picture of John Brown as a monumental figure holding a Bible and a rifle.
That's about it for touristic things in this part of KS.

As far as sights to see, consider seeing KC attractions before you drive to Ft. Riley.
Ah Kansas; so much to see and so far apart...I've lived in this state for most of 51 years and feel I've not seen much of it.
It tends to get windy here in Kansas...well, most of the time -- so make sure you cover as much of your body as possible. Cold isn't bad. Wind makes cold bad.

The Kansas Cosmoshpere and Space Center is in Hutchinson about 2 hours southwest of Ft Reily its pretty neat.
The worlds largest handdug well is in Kansas as well.
