RE: Traveling the Oregon/California Coast in July
Lots of campgrounds along that route (101 and 1) but I have no experience
during the 'season' along there with camping.  I can tell you to expect
heavy traffic all down the Oregon coast and down through California.  And
heavy traffic through there means slow traveling.  But a great drive, I've
done it in both directions a couple of times.  Also be aware that Summer is
the time they will be doing major repairs on the roads, especially along Hwy
1 in California, got to fix the damage that occurs most winters along
there.  Both Oregon and California have Websites with highway construction
info.
