That's really bad luck !

I have to do with it but is there a good way to deal with it.

For the CA-1 part:
Should I still try to reach Cayucos from LA on day 19 and then take the road 101 to Monterey on day 20 ?

Or should I let the CA-1 down and privilege LA or maybe a 1 day visit of San Diego ?

For the Mariposa Grove issue:
I really don't have any idee. I had in mind to take the road 49 from Sacramento directly to Oakhurst and take a look the same day to the Mariposa Grove area.
I also have a night already booked at Oakhurst.

Shoud I find another place to spend the night on day 6 and try to reach the Yosemite Park from the north entrance ?

Any idea is welcome :-)
