I'm truck driver and sometimes I drive through California. Is it possible to park semitruck on parking area next to museum to look at exhibits?

Tons and tons of room, but only one way in or out so plan ahead for that part if they get busy

Yes

Plz contact the museum directly, why? The museum might have a special delivery on the same date you are planning to park.

Plenty of room but call ahead.

No problem from what i see.

There's certainly enough room
