Simplified metaphor explanation for non climbers. 5.x is a rating of climbing difficulty.

5.7 - vertical rock reasonable holds, usually takes training, skill, lack of fear to climb. Most somewhat athletic folks, working hard could get up this.

5.10 - used to be the limit of what was climbable(1950's?). Subtle climbing, only small things to hold on to. Very hard. Most folks could never climb something like this.

Thanks for the post Chris.
