In the United States all radio and television stations are represented by "call letters". Each set of call letters is 4 letters long. Call letters for stations east of the Mississippi river begin with a "W", while stations west of the river begin with "K".

Using the description of their station and/or the format, figure out the call letters of these fictional stations. (E.g. A station for people getting their affairs in order before they die might be WILL)

Note: Some stations will use phonetics as opposed to exact spelling.

West of Mississippi River:
1) A station for felines.
2) A station for kids going away for the summer.
3) A station for pessimists

East of Mississippi River:
1) A station for those who like to do something between running and standing still.
2) A station for people who like to be ankle deep in water.
3) A station for Capt. Ahab and his crew.
