That great post-secondary winter sport, traybogganing, may fall victim to the push to save money at universities and colleges.

Traybogganing, as many student blogs make clear, uses (borrowed) cafeteria trays to slide down snowy hills.

"My tray went out of control (well, how can you control a food tray?!), so I hit several snowdrifts .... But it's so much fun!!," one poster reported.

It is a well-known entertainment at many secondary institutions, a break from the books or a cool end to a pub night.

A number of U.S. schools, however, are trying to save money by pulling the trays, which will save money on water and cleaning bills (and may reduce food waste, although some students say they'll just make repeat visits to the steam table), the Associated Press reported.

According to U.S. food-service companies, hundreds of colleges and universities are going trayless.

One company, Aramark, surveyed 92,000 students, faculty and staff at 300 schools and concluded that almost eight out of 10 would be just as happy eating from plates as from trays.

Clearly not winter sports fans.
