Thanks Eric, keep us posted please!
Looks like a paved 'exit' road at the end of the gravel trap, presumably for giving the Manitou easy access in case it has to come out (and it will!). Also hoping there's enough space between the wall and the safety fence for the Manitou to go thru in case it has go down all the way towards the end of the gravel trap - there's an another opening, right where I think marshals post 125 will be.
@CTD: you are referring to marshal post 123.
