Department of Horticulture students placed sixth nationally in competitions at the 1996 ALCA (Associated Landscape Contractors of America) Student Careers Days at San Luis Obispo, Cal. Bryan Gooch, graduate student in CSES, won first place in the turf and weed identification competition.

This was the team's second year participating in the event. The team rose from last year's eleventh place showing in events ranging from a business-management problem, to a landscape-design event, to a competition in driving a Bobcat, according to faculty sponsor Robert McDuffie.
