Transportation to Muir Woods? Planned a trip to SF in late June/early July 2021 &amp; would like to visit Muir Woods.  Unfortunately, just discovered that the shuttle to Muir is suspended due to Covid restrictions.  I've also heard that Uber can get me there, but w/o cell service in the Woods, I'd have no way to book a ride back to the city.  Looking for any suggestions on alternate transportation, or any hope for the shuttle resuming?
