	This past Sunday, Au Sable&rsquo;s Great Lakes and Costa Rica campuses went from the silent beauty of spring wildflowers to the low buzz of student and faculty activity.&nbsp; The spring and summer academic year commenced with students embarking on classes in field natural history, ornithology, and tropical agriculture and missions.&nbsp; These courses prelude the 19 classes to come during our summer session courses scheduled for this year. The complete lineup includes classes at four campuses: one course in India, one course in Costa Rica, four courses at Pacific Rim Institute, and 16 at the Great Lakes Campus. Currently, 81 students from 28 different colleges and universities will participate, filling 146 course slots.</p>
