Up The Cliff:
The colored lines represent ropes. All PCs are roped together using the black rope; Billie is not attached to this rope. Rather, Billie is roped to Zach, Jacky, and Thrud using the blue rope.
Vasco was on the 5th line? If so, that sounds fine with me. And I agree with Matmaisan. Didn't get home till late last night so no time to draw Pic. Will try to get on it asap
