Narrative:

Flying at 3000 ft north of tecumseh airport monitoring detroit approach, I hear approach talking to a plane calling traffic at 4 mi sbound at 2700 ft. I assumed I was the traffic and started looking for this other plane. While looking I spotted several parachute canopies to the south and west and altered course to the east. Later I heard a plane ask approach if they were talking to the plane near the airport. They said no. The plane then said he was going to follow that plane for a while. I continued on a southeast heading to almost monroe, mi, when I noticed a large turboprop twin at my 8 O'clock position, very close. I broadcast on approach that I had the jump plane off my wing to establish communication. The other pilot expressed his displeasure at me flying over an airport 'without talking to anyone.' I explained that when I saw the jumpers I altered course and I was sorry. Both planes resumed normal navigation. 1) I was monitoring approach but heard no calls about parachuting. 2) the jump plane was very close to my altitude 500-1000 ft away with no communication between us.
