Here's the road sign Brooke and Claire are driving by, I would guess they are driving from the airport to the first clue and ditch the cars somewhere. I couldn't find the same sign; this is the closest approximation. I wonder what's out there in Guri. It's true that the 43 is a straight shot to Cheorwon (rafting), but if you're coming from the airport there are easier ways of getting there. And to get to Guri area they would have already passed the palace seen in the intro caps.
Brook/Claire are on Highway 6 eastbound in Guri
because making a left onto Highway 43 (northbound) takes you to Donggureung (or Donggu-Reung) which is immediately north of Guri
(It shows up as a green blob on the Google Maps.)
Since Incheon International to Camp Casey skirts northern Seoul, and here they are in eastern Seoul.....so either they could be lost on the way to the rafting, or lost on the way to Camp Casey after finding the palace, or maybe another Route Info stop.
Can anyone figure out caps 20-25??
It is a bit unusual to have that many frames of just a location shot...so makes me wonder if it is significant somehow?
It looks church-y, to me. Maybe it's taken from when the teams are cutting through Seoul to get to Guri....it's almost like they are on an expressway viaduct in an urban area
