Lynn, ooh, thanks for the recommendations on stops. I might start an off-topic thread about favorite spots along the coast to learn more from those of you who have done this before. I'm now debating whether to do north or south on Hwy 1 after LAR101's comment (we're driving both ways, but will do I-5 one direction, because it's about 10 hours shorter). I will confess, though, fleece just isn't my favorite, less due to fashion than to comfort.
GillianPearl, oh, good call on the split back and the wind! I wouldn't have thought of that. That particular top might be better as a before/after piece for yoga or dance workouts, but for now, I have something that fills that niche.
Sloper, I would never have thought of Universal Standard for this, but you're right! They really seem to looooove high crewnecks there, but if I decide to go with a zip-up option they have some great ones.
anchie, too funny! We supposedly have a "Mediterranean climate" here in LA, but they really just mean dry in summer and wet in winter. Nights get chilly almost year-round, even this far south!
Jonesy, that sounds like the perfect "just after college" trip. I'm pretty sure my 20-yo son (who isn't going with us on this one) yearns to crisscross the country with his friends a la Jack Kerouac.
ETA: I've put a couple of orders in and will report back!
