Just a couple comments from a first time poster. I like reading these because it isn't a 100% spoiler, mostly speculation based on deduction.
In the ice cuting photos, the bank looks closer with Eric and Jeremy, I'd guess that means they got there first. The cameraman has turned around to see the hippies, the other bank is farther away, with a set of cutters in the background. Probably Rayo is last. Could be wrong about that.
In the clip showing them on the rollercoasters, either Eric or Jeremey says How can you read anything up here, or something like that. Probably means that is a roadblock where you have to read something (maybe ground level, maybe up in the air) in order to get the next clue. I bet Tyler could excel there, since he could more easily get help from locals.
Go hippies!
