Concealed is fine, even past normal buster signs. The ones that you can't carry past are the ones that are a larger red lettered white sign. Those are the extension sign. Those places have an extension to put security in place. Those and federal buildings are a no-go. There are a few cities/counties that are bucking the state law of allowing open carry. Johnson is one of them. There is a bill that is being voted that wool not allow cities/counties to preempt state law. I live in the Wichita area. Open carry is fine here. One thing I will say about Kansas, I do like the proactive 2a work that had been done. Banks, churches, even schools that don't have the extension, concealed is okay. Plus, Kansas has reciprocated with many other states.
