Wow...MD is a long way from the west coast...what happens once you get to SF...???
What type vehicle are you driving...???
Just before you get to SF on Calif Hwy1 is the city of Pacifica...check out Gorilla BBQ...located in a converted railroad boxcar...
Calif Hwy 1 IS the coastal route...slower, and be prepared for LOTS of twists and turns as the highway snakes around bluffs, coves, and gullys (it can be fatiguing if you're not used to it...take your time and take lots of breaks)...
US Hwy 101 is faster, but not next to the ocean for the most part, this is Steinbeck country...think of Tom Joad (Grapes Of Wrath), and Cannery Row...
Interstate 5 is an express route, fairly barren, and to some it's a soulless route...it's function was to provide a faster route between LA & SF along the western edge of the Central Valley, faster than US Hwy 101 , or the eastern Central Valley route Cal Hwy 99 (used by lots of trucks)...when I-5 first opened there weren't many gas stations or food places...it's improved since then...my personal nickname for I-5 is "The Leadfoot Hwy" due to the high speeds folks zoom along at...
BTW...the Central Valley,
et al, is the
Sacramento Valley in the north, and the
San Joaquin Valley in the south...the terms are sometimes used interchangebly...
Leaving LA, US Hwy 101 and Cal Hwy 1 are the same chunk of pavement, but NW of Santa Barbara, Cal Hwy 1 splits off at Gaviota and skirts around Vendenberg AFB, wheras US Hwy 101 heads north to Santa Maria...
IF you decide to take Hwy 1, you can still get to Santa Maria on Cal Hwy 166 to enjoy some Tri-Tip (aka Santa Maria sirloin cut)...
At Arroyo Grande Cal Hwy 1 and US Hwy 101 rejoin until you get to SLO (San Luis Obispo), where the 2 highways split off again, with Hwy 1 rejoining the coast at Morro Bay...SLO is roughly your half way point...(while there in the SLO area tune in KPYG-94.9-FM)...
Places you may want to visit:
Hearst Castle at San Simeon
The California Missions
(north of San Simeon and up to Monterey is Los Padres Nat'l Forest)
Monterey Bay Aquarium & Carmel By The Sea
Santa Cruz Boardwalk (while in the Monterey / Santa Cruz area tune in to KPIG-107.5-FM)
On the north end of your route is the infamous Devils Slide, subject to continous erosion...the bypass tunnel is scheduled to open by the end of this year
According to
mis-information by Al Roker on a tv show, PCH (Pacific Coast Hwy) extends from San Diego to Seattle...which simply is NOT the case... here is a
LINK to Wiki Info (
http://en.wikipedia.org/wiki/California_State_Route_1) (to us native folks in the north, PCH is a southern Calif thing)...
At different points Calif Hwy 1's name is PCH, Cabrillo Hwy, Shoreline Hwy, and Coast Hwy.
I created a map that might help you visualize the different routes:
