Could someone tell me why we could not lay natural turf down for the summer and move it off the field for the off-season? Didn't they have to do something similar to that for Moscow and the Champions League final? I remember seeing them with turf being grown in boxes and were going to lay it out for the final. It's not as complex as the one stadium in Asia where the turf is rolled in and out depending on the event. The sections could be removed and kept somewhere like Downsview in a greenhouse or something similar so it could be maintained over the winter. In the summer, irrigation could be achieved by capturing rain water from the Ricoh and other CNE buildings. Spare sections could be maintained in the event there is too much damage in the penalty areas.
