There is no such thing as common sense.True and it just increases the number of idiotic things that happen nowadays where people do things that are clearly stupid but haven't been specifically warned not to instead of using their common sense.
Calculated risk - yes. Be that used the route descriptions etc or if unsure request assistance ( may be with a few bers and a meal for giving free time).
The "common sense" would be the one that allowes you to do it most confidently and safely.
In which case the OP was correct and your proposal is the stupid risk - that may get some of us out of beds due to a call out.
