The Thirty-Third Summer Symposium in Real Analysis (The Tall Grass Prairie Symposium) was hosted by SoutheasternOklahoma State University, June 23--27, 2009. The Editorial Board of the EXCHANGE wishes to express its gratitude toSoutheastern for its gracious hospitality and to the conference director, Patrick Reardon, for his outstanding leadership inorganizing and conducting this symposium.

In addition to the formal mathematical program, time was set aside for research collaboration and a problem session. OnThursday afternoon, the symposium participants were treated to an informative and entertaining excursion to the nearbyHeadquarters and Museum of the Chickasaw Nation.

On Friday afternoon, the participants honored Jack Brown of Auburn University for his many contributions to the realanalysis community. "Testimonials" were given by Udayan Darji and Patrick Reardon, two of Jack's Ph.D. students atAuburn University. A slideshow of action pictures of Jack and Jane at previous symposia and mini-conferences was shownand presented to Jack who was (reluctantly) in attendance.
