It just depends on if you feel lucky.
It doesn’t necessarily look good. First of all, that point is – if accurate – just outside the closure area from the Lake Fire.
If it’s not accurate, however, that’s a heck of a slog to run out of (legally accessible) real estate.
Beyond that, assuming it is accurate, there’s a reason why it’s called Hell For Sure Canyon. Yes, there are some incredibly steep areas. Oh, and mountain lions.
Sorry man, sounds like an awesomely fun project.
