Approximately thirty members of the PAAA became airborne en route to Perugia, Italy to partake in the 6th International Congress on Aerobiology held August 31- September 5, 1998. The meeting supplied 133 oral presentations made during 26 scientific sessions, 7 Plenary lectures, and 6 Satellite Symposia. In addition, more than 100 poster presentations were made during 6 sessions. The meeting was a huge success. We extend our sincere thanks to Guiseppe Frenguelli and the organizing committee for providing productive scientific sessions and genial social gatherings.
