Narrative:

While departing runway 22 at I69 airport, another aircraft was sighted doing a fly-by over the west taxiway heading northbound. During taxi out, an unknown observer to the east of the runway radioed my aircraft and asked my intentions, and also informed me of an air derby in progress. I replied that I would be departing runway 22 with a left turn out for a northbound departure. After performing before takeoff checks, I announced my intentions for takeoff, visually cleared the pattern, and began my takeoff roll. During the takeoff the unknown observer advised us of an inbound parachutist of the derby approaching head-on. My CFI pointed out the traffic which I acknowledged immediately. I continued my climb and remained clear of the traffic. With the observers on the east side of the runway this may have appeared much closer from their view point than it actually was. With several aircraft performing these unusual fly-by's the airport should possibly have been notamed closed.
