Narrative:

Proceeded nne VFR from nash field 4 mi south of indianola, ia, intending to fly to area east of des moines and then proceed west to land at des moines. Visibility at indianola was 4 mi and pilotage difficult. When I realized I might be under the outer portion of the outer ring of dsm class C airspace southeast of dsm airport, I promptly turned right to the east and descended. At this point I may have been over 2200 ft MSL (the outer ring floor) by 100 ft or 200 ft. While east of des moines, I was at +/-1500 ft MSL and was cleared to proceed westerly to des moines for landing. I was vectored wnw, then south and turned southeast on final for runway 13L. Upon approaching the inner portion of the class C airspace at 1500 ft MSL, I was advised that I was under SVFR, which was acceptable to me, although I should have but did not request it.
