Hi All
Started with Pat 12 because of these photo

Shows the fairly steep launch down the ramp not something you would be doing with the same truck every day

Probably fairly common operation driving through streams wading for the Pat 12 Fording for the Jeep.

Pat 13 the guys on the roof you got to wonder may have done this a time or two.
I suspect the first and last trucks pictured would get attention after landing, the truck crossing the stream oh just another stream and on with the job.
Cheers Phil
