Setting up an anchor
|[ Sizes: Orig | Large | Med | Small | Thumb ]|
Yes, we put biners through the trailer hitch and the my car was the anchor. It was in park, hand break on, and we backed up the anchor with nuts (sizes 7 and 8) just in case :) I wanted my car to hang on the rope, and not to fall down into the canyon.
And for difficult routes, one can drive the car while the climber gets up.
