It's still not clear to me what's open and what's not

Big T is open to Angeles Forest

Angles Forest is open to Red Box (@Angles Crest)

Angles Forest is open to Upper Big T

Upper Big T is open to Angeles Crest

So what happens when you get to Angeles Crest @ Red Box?

What happens when you get to Angles Crest via Upper Big T ?

Please correct any false assumptions.

Oh and I thought snot was weakness leaving the body.
