I concur. I have been living/commuting from Carlsbad to Torrey Pines for about 6 years now. We are looking to buy mainly in the Carlsbad area. Buying in North Carlsbad would add an extra 10 – 15 mins commuting time which I don’t know if I would be willing to put up with. However, I have ruled out any area that requires taking the 56. Over the years I have put together a system that helps me beat traffic going north on the 5 corridor. It may not be real, but it seems to me that there are fewer traffic alternatives traveling to points east on the 56 than traveling north on the 5 corridor.
