That may only be part of the game. If there are cans involved, they'll probably just be mixed together or something, or have the labels erased. The only problem with soda cans is that if a robot runs over one... that could cause some major issues. First off, you'd be going through cans like mad. Second, those who use thin pneumatic wheels may (though I doubt it) risk a puncture running over a can. And, it would be hard for rookies. There needs to be a basic "pushing" scoring method, without using the cans. I dunno. Sounds more likely than anything else put forth though. And yes, Elgin Clock posted his theory that 55 gallon drums would be involved based on a FIRST Email blast. I think he was right. We'll just have to wait and see...

edit:
Ok, I just reread the previous post and I see he stated plastic 2-liter bottles. That is kinda likely... but you'd still go through them kinda quickly.
