Q&A: De-car-ing in the Valley
Your eco-questions answered: 
Question: I was reading your blog and noticed that you've been hanging out in the 818 (the Valley). I recently just got rid of my car (long story, but it was a lemon) and have been somewhat car-less for the last couple of weeks and enjoying it. I freelance, so I commute only about twice a week and for those occasions I carpool with my husband (he still has his car, hence the "somewhat" car-less).
Anyway, I was curious how you traveled to the Valley from Santa Monica. I ask only because I'm trying to gather other recommended modes of transportation from fellow car-less folks. Did you cab it or do that hourly car rental thing (forgot the name)? I live in the Valley and I love to hear the best way you've found to travel between the Valley and Santa Monica. Cheers, Liza
Answer: First of all, congrats on the de-car'd lifestyle! Second, it's car-free, not car-less :)
Third, to say I've been "hanging out in the Valley" is not quite accurate, especially as I have many readers who get angry because I allegedly don't give the Valley enough attention or because I make fun of it (my ribbing's just jovial teasing, people).
In any case, I only go to the Valley a few times a year! It's simply that I happened to make two trips last month. Once in a blue moon, I have to rent a car for the weekend -- and when I do, I make a trip to a relatively faraway L.A. spot and hit all the places there I've been meaning to visit. That's why I have a buncha recent posts highlighting places in the Valley -- all of those were from one trip.
The second trip was to a party at my friend's who'd just moved to the Valley. I did that by bus, and it wasn't a happy trip due to the buses not showing up or being late.
This also answers your main question: No, it is not easy getting from Santa Monica to the Valley sans car, IMHO. However, I did notice that the Valley itself has gotten somewhat nicer, with lively shopping and arts districts, colorful sidewalks, etc. The main concept of de-car-ing isn't so much about taking public transit to far-off places, but being able to avoid having to travel far at all because you have everything you want and need near you. For ex., lots of people in less-than-lively places in the Valley (and the O.C.) drive into Santa Monica and spots in L.A. because they have no good shopping/restaurants/bars near them -- at least not more than 1 or 2 (which one can get tired of relatively quickly).
What I'm saying is, if you really need to get to Santa Monica or environs relatively often, not having a car may not work so well right now, unless you have a masochistic streak. (Though I'd say any driver who fights traffic to cross that distance on a regular basis also must have a high threshold for pain.) A cab ride between the Valley and Santa Monica's gonna be quite pricey -- and Flexcar, the car-sharing service you were referring to -- has pulled all the cars out of its L.A. locations except at USC and UCLA.
So what I'm wondering is if you live in a part of the Valley where you have easy access to important amenities. If so, definitely stay car-free and just borrow your hub's car once in a while when you need it.
Part of the de-car-ing effort might simply be an adjustment in your habits, i.e., finding more fave restaurants in the Valley instead of sticking to the tried-and-true ones you may have in the Westside. It may take a lil more effort at first, but over time, you are likely to derive more satisfaction from discovering nice neighborhood spots that become your new favorites that you can walk or bike to.
Lastly -- If you bike and can do the bike-plus-bus thing, you may very well be able to travel between the Westside and the Valley with relative ease. Zach Behrens, editor of LAist, lives in the Valley and manages to get all over L.A. sans car. He does, however, still own a car...
