Must be different for each staff. The hump we did for SULE II had a **** load of hills, and we were going single file through the woods in some parts of it. It was kinda bizarre. I had no idea what the hell was going on.
Walsh wasn't talking about danger, but just physical difficulty. That first hump goes over Da Nang and a few other fun hills east of of Engineer road. The later ones are just long, and since they're half at night, are slower.
