Pointers in San Diego area?

[Hannu Saarenmaa]

I am a lepidopterologist from Scandinavia that will be visiting San
Diego, California, on May 6-12.  If any locals are reading this, I'd
appreciate pointers to places to visit.  Moreover suggestions for
accommodations outside town but not too far commuting where I could stay
and put out my light for moths would be welcome.

Thanks in advance,  Hannu Saarenmaa
