SoCal;
AAA Autoclub Bakersfield/Famoso Raceway {brackets or drag races}
AAA Autoclub Fontana Raceway {drags or Roundy rounders, Legends cars etc.}
Santa Barbra, Malibu, Huntington Beach, Ocean Beach, Pacific Palisades
Pebble Beach, Moro Bay area/Bayonette if your into golf,
or Monterey area & 17 mile drive in really nice too
Laguna Secca/Mazda Raceway
Pacific Coast Hwy, especially in LA area
Monterey Bay Aquarium
Pretty much any of the 100's of Cali beaches, except maybe the nude beaches...
Hwy 1 Coastal Hwy is pretty cool & scenic too, especially great if you bring a lady...
{I say don't bring sand to the beach thou...LOL, if you get my drift ?}
Maybe take a surfing lesson or go on a Hobbiecat or Wave Runner
Bobs Big Boys in LA/Burbank {?} area
{I cant remember where, I'm tired & my sometimmers acting up...LOL}
Pinky's Hot Dogs Hollywood area
for cruise/show nights etc. check the -www- google search
But, I'm much more of a NorCal guy thou,
someone from SoCal could speak to the cruise scene far better...
Van nuys Blvd & Colorado Blvd were a historic cruises,
parts of old route 66, Mulholland Dr. {windy curvy rd. famous/infamous street/rd.}
some are still kind of cool too
Have fun & enjoy SoCal & CenCal,
Make sure you bring & wear good sun block & sun glasses,
bring lots of shorts, cool shirts & sandals maybe,
it ain't the great white north, it will be warm/probably hot no doubt 90*f-100*f+...
NorCal;
Redbluff & Redding area have some cruises & a Dragstrip too
Lake Tahoe Hwy 80/50, awesome area beautiful country {touristy thou}
Any of the Motherload off Hwy 49 & Placerville, Grass Valley,
Georgetown Hwy 193 & east-Calif area off Hwy 50 or Int. Hwy 80 area too...
Some cool areas Gold Country too, Coloma gold discovery site,
right on the American river, even great white water rafting if you want...
&/or maybe Sutter's Fort & the Capitol in Sacramento...
The larger cities are scum for the most part,
{I was born & raised here, I love my state BUT, I know where not to go too}
unless it's in the touristy areas, it's pretty tame...
I'd suggest stay to the country off the beaten' path if you can...
Not trying to scare you or deter you from coming to Cali, it can be great !!
just be aware of your surrounding, especially in the inner-shity's...
Alameda, Benicia & Vallejo {even Port Chicago, by Concord/Pittsburg}
are old historic military areas...
There area some great places in the NorCal Sacramento River Delta too,
hwy 4 & hwy 160 or even parts of hwy 12
S.F. not my favorite place at all, Alcatraz Isl., Presidio, Treasure Island too
but lots of cool stuff to visit, especially on the waterfront & Piers, SF Bay Aquarium,
Giants Game PacBell Park, A's game Oakland Coliseum Oakland & SF Zoo's
{Touristy Pier 39 & Embarcadero areas}...
Santa Cruz Beach Board walk, various old rides & souvenirs,
live music occasionally, surf, sand, critters to watch...LOL
IIRC they have a few cruises here & there too,
no idea of dates or if organized either, haven't been in a while,
especially anything along/on the water/beach front...
Yosemite Nat. Park, is beautiful right now, it's probably crowded thou...
Watsonville, Calistoga, Antioch, Sacramento, Stockton
all have decent either dirt &/or paved roundy rounder tracks
Sears Point/Infinion Sonoma & Sacramento Raceway of Hwy 16,
both Drags weekdays IIRC Wed. evenings & some weekends too...
RV would be a great idea,
RV Parks/spaces are hard to come-by in the summer,
some campgrounds have size limits too
we have some great Forestry, 100's of Lakes {albeit low}, multitudes of great fishing
Rivers, Recreation areas, National Parks & great Campgrounds here
OK that's enough...LOL
I could probably go on & on...
Good Luck & happy Moparing
