Narrative:

Local flight from winder, GA, to gwinnet county airport, GA, approximately 15 NM distance on cavu day. Approaching gwinnet (lzu) I called 10 mi east for traffic and runway advisories on CTAF, 123.05 just like I have done for yrs. No reply, but sometimes they are away from the radio, so no big deal and I pressed on. I could see aircraft taking off and landing on runway 25, so I set up for that calling downwind and base. Then someone (unknown) called and told me that gwinnet tower was now in operation on 119.15. Not wanting to make a bad situation worse, I made a go around and switched to tower. They cleared me for another pattern and normal landing. This was notamed, but really -- who checks NOTAMS for a 15 mi flight on a beautiful cavu day? Me -- next time!
