Hate to break it to ya, but this year, they illegalized hog hunting of any sort in Kans-azz in order to eliminate the illegal importation of feral hogs into the state. Now, you need to jump through a bunch of hoops just to get a permit to shoot them. I used to live in Wichita and I did see one on the side of the road where K-15 meets I-135. Take a look through other posts on here and you'll find actual correspondence between one of us and the KS legislation.
Peace out and good luck...
