I had just entered the outside lateral boundy for Fort Wayne class C airspace.  I stayed below 2000' MSL and had the radio tuned to approach/departure control for west of active runways at 127.2.  I never heard a peep from them.   If I would have thought about it at the time I should have tuned to ATIS on 121.25 to get any special information.  Maybe that's why I never heard anything on 127.2.   They might have been handling all approach/departure traffic on another frequency.   If this route had been in my original flightplan I would have done exactly that but planning in route never seems to have enough time to really think about these details.
