Severe clear today, so other then the safety net of ATC services, weather
wasn't an issue.

Coming back from HBG (Hattiesburg MS) to MBO (Madison MS) encountered the
following exchange with ATC. I was already told to expect the visual
approach in my inital contact with approach controller. Frequency, while
not wall to wall traffic, was busier then normal.

ATC Sundowner 1943L, descend and maintain 2000, report Madison in sight.
Me 43L will report Madison in sight.
Me Approach 43L, has Madison in sight
ATC 43L radar services terminated, squawk VFR, have a good evening
Me Uh, 43L would like to cancel IFR at this time.
ATC 43L radar services terminated, squawk VFR.
Me, Uh, will assume IFR cancellation received, squawking VFR, good
evening.

I change to Unicom and land as normal. After landing, switch over to
Clearance and Delivery (CD) to see if indeed my IFR cancellation was
received, but it was busy with the controller handling approach and
departure traffic (one guy does all I guess?) so I didn't interrupt the
frequency.

Took my time tying down and hung around for a bit just in case ATC called
the airport, in which they did not (seen this done many times when IFR
traffic forgets to call CD) so I felt comfortable that the airspace was
re-opened for arrivals.

Queston one: I never was cleared for the visual which caught me off
guard on my forth line, and since it was severe clear, I figured go ahead
and cancel my IFR thus negating my need for the visual clearance. No
biggie, but shouldn't I have been cleared for the visual before radar
services are terminated?

Question two: While I wanted on the tapes that IFR cancellation was
received (see last transmission by me), was I truly and properly
cancelled out of the IFR system? Since the frequency was busy, figured
to let sleeping dogs rest, but I wasn't comfortable with the fact that I
didn't hear the buzz words "IFR cancellation received".

Question three: Is this worthy of ASR filing? No safety issue by any
means, but there were areas left wide open for miscommunication (I.E. not
getting the airpsace freed up for the next IFR arrival).
