Bill's Facebook post says "the first FRC game hint (that we're admitting to)" tells me that there are other hints out there. In his previous posts we have seen:
* stair picture
* "hang in there"
* "stand by"
* Two steps forward, one step back
* View from 30,000 feet

I would think one or more of those could be additional hints, as it may relate to this picture - its setting, the artist, orientation, songs, etc.

My $0.02
* reversed train tracks - above the field, not on the field.
* bots that have to climb up or attach to tracks
* move on tracks
* hang on tracks
* vertical movement
* field elements above the playing field
