I am a huge fan of driving.
I wake up before sunrise and get out of the house just to drive at least once a month, sometimes more. I rarely have a destination, sometimes don't even know if I'm going north or south, but almost always drive the coast. The midway point is nearly always me stopping on a beach, hanging out for about 15-20 minutes and heading home. I usually try to bring something home - a loaf of bread, bottle of wine, something.
The Brand has no interest in coming with me and that is perfectly fine by me. She prefers her sleep and I think she knows I prefer to drive alone (or at least to control the soundtrack). She's always welcome of course, and I bought a dash cam to share some of the best parts of the drive with her when I return.
I also buy cars with this in mind - will it perform well on PCH? I was on the verge of buying an old 911 when we met, so the Macan was a temporary compromise just in case we had a child. So I guess that old 911 is little longer off - when she was first born though, I would take her with me, feed her on the beach and she would sleep in the car seat most of the way there and back.
So no - you don't have to feel badly about not going to the same extent that she shouldn't feel crazy about driving a long way just to see the ocean. She should find some fun, different roads though just to make it interesting. And a good soundtrack.
