War stories, tips, or thoughts are appreciated.

So if I have a cable going across 10 equal spans, is the tension in...
IBC requires guardrails on ramps if adjacent to a 30" fall. IRC requires guardrails on porches and balconies. Is there any code or standard that requires guardrails for a residential driveway adjacent to a hypothetical 100 ft drop?
