Narrative:

I was on VFR flight following with regional approach. During normal; level cruise flight; what appeared to be a piper cherokee; ascended from my right lower corner of the windscreen and appeared to level in front of me. I immediately turned to the right to provide separation. The other aircraft then slowly continued to climb to the left out of sight. The aircraft I was flying has traffic information system (tis) onboard; but there was no indication of the aircraft prior to it suddenly appearing in my field of vision. I work hard to see-and-avoid traffic; never fully relying on the ATC or flight following. I asked approach if they had the traffic; but replied they did not. I am not sure as to whether the other pilot ever did see me; but either way it was too close for me. Especially on the heels of recent events involving a similar situation. Other than ensuring that I continue to scan for traffic I am not sure anything else could have been done on my end. All pilots need to actively participate in see-and-avoiding traffic.

Title: A VFR Cessna 172 and a PA28 experienced an NMAC. Neither the Cessna's traffic information system or ATC Flight Following radar sensed the other aircraft.
