Narrative:

Enroute to my filed destination on IFR flight plan. Visual conditions. I did not cancel my IFR in the air with the controller. Once on the ground I had an extended taxi to the ramp due to a special event with multiple taxiways closed and; part of the ramp closed and difficulty finding a parking spot due to the special event. This delayed canceling my flight plan.contributing factors:1) no aerodrome NOTAM for the special event. A NOTAM would have alerted me that this small airport would have been congested.2) unable to receive AWOS until 7 miles from airport. This was the first notice that I had of a special event. The AWOS information included a very lengthy list of areas of the airport that were closed. I'm curious as to whether there is a problem with the AWOS transmitter because one is generally able to receive the AWOS/ASOS etc. From at least 30 miles at most airports. I would be in favor of a better way to cancel IFR flight plans at small airports as the aircraft exits the runway.
