SF Bay Area to San Diego

Hi,

I'm planning to make a trip from RHV to MYF in a C182 this weekend and
back. I could do some really mild IFR, but I'd really rather be VFR.
Although I got my IR last year, I don't have a lot of hours (250 total
and only 15hrs in the previous year) and feel nervous when I have to
travel through different WX system. What I'm facing? Will I be making
any mistake by choosing the inland route vs the coast one (or vise
versa)? I'd imaging coastal flight would be pretty. In the SF Bay Area
you could almost get away with VFR locally even there is a winter
storm nearby. What about the SCal?

Thanks a lot for any tips and help,

Jizhong
