[Monty Python]

So it mentions two obstacles, the bridge and the hurdles. This could be literal and we might have some giant field object that makes movement difficult (a fairly safe bet, considering there's been something that impedes movement at least a little bit every year of FTC). My guess would be something to do with hanging. You can hang off of bridges and hurdles, and we're overdue for a hanging portion as we haven't had one since 2006. Most FTC teams have never had to deal with hanging and so this could be a great new game challenge.
