Daily Bulletin, Friday, September 9, 1994 ORIENTATION brings chiefly social events today and over the weekend. Among the highlights: Frosh Olympics from 1 to 3 today at the Village Green and Columbia Field, followed by the Campus-Wide Chariot Race from 3 to 4 in the arts quadrangle area. Green Spirit and Shinerama tomorrow from 9 to 1. Shinerama is a longstanding Canada-wide program that raises money for cystic fibrosis research; students shine shoes, car windows and anything else that will hold still, and invite cash donations. Green Spirit is a newer project that's grown in scope and enthusiasm over the past couple of years. It sends students out to plant trees, clean up trash and do other environmentally friendly things around Kitchener-Waterloo. I haven't been provided with any details on the 1994 projects yet. Toga at the Yoga on Saturday night, and Village Night at Federation Hall. Today's the last day for registration at the Physical Activities Complex. Starting Monday -- classes start Monday! -- anybody who hasn't registered yet will have to do so in Needles Hall, and will start paying late fees. IT LOOKS LIKE a bodacious weekend for outdoor activities, such as the Math Faculty Computing Facility staff picnic tomorrow afternoon. Then on Sunday comes the Corporate Challenge, one of the most cheerful and silly events of the year, which invites teams from major employers in Kitchener-Waterloo to compete in so-called sports and games. UW's team is captained by Keith McGowan of the arts computing office, who'll be hoping for a more distinguished finish than the 1993 team achieved (25th in a field of 58 teams). The Challenge starts at 9 a.m. and runs for most of the day in Waterloo Park. Spectators and cheering sections are welcome. OTHER NOTES: Saturday is Goods Exchange Day in Kitchener-Waterloo, when householders are invited to put unwanted household items out by the sidewalk, and passers-by can help themselves. Electrical power, heating, cooling and ventilation will be turned off at the Columbia Icefield on Monday from 8 to 11 a.m., so that plant operations can do preventive maintenance on electrical equipment. The shutdown will also affect the gate for parking lot W. Birthday greetings to Mary Thompson of the department of statistics and actuarial science.
