Generally, when the Maritime Academy puts up a tent, it is just below the "Bell" area. Yes, it would take up some of the area, but the field is huge and the tent shouldn't interfere with the seminars.
If you haven't read the Spring/Summer Newsletter (link on the home page), please check it out. I'm trying to find dojo that will sponsor an Okinawan for camp. I'd like to see at least a couple of Okinawan teachers at camp this year. How about it, you seniors? Start some fund raising and bring over your favorite Okinawan sensei. Call me for details. Your dojo will be hosting him for at least a week and the camp will host him for the three days. Win-win situation for all.
