Yep, but they're easily available from the cafeteria right when the blizzard hits. Right when other sledding equipment is likely to be sold out from stores (stores that don't sell commercial-grade trays, at any price..). Plastic sleds (especially the flexible rectangles with the single handle) are cheap in bulk - maybe stockpiling them on behalf of the would-be tray borrowers, could help?
