Narrative:

I made 4 attempts to contact bwe FSS on 123.6 for advisory with no response. After making approach and entering VMC conditions, I asked ZME for the winds at bwg and received WX that was 1 hour old. I cancelled IFR at this time and was told to squawk 1200. I did, and tried bwg FSS 1 more time on 123.6. Now bwi answered and informed me that I was in a control zone west/O an IFR or special VFR clearance. I requested the special and was in the flare by the time I repeated the clearance; ie, 1) mem ARTCC was very busy; 2) bwg's lack of response to me and no other talk on radio led me to believe another FSS was closed; 3) I saw rotating beacon on, but did not dawn on me there was an active control zone because...; 4) I was in the landing phase of flight and looking for traffic from the time I cancelled the IFR clearance to landing about 1 min.
