A couple months ago, B and I roadtripped from SF to LA (we had some business in Silicon Valley again). The I-5 is such a boring route, especially when you do it often. Fortunately, I frequently get to be the passenger and am able to take photographs along the way. :) I don't recall what the white sticks were (probably for crops). The clouds were definitely an added bonus to what would normally be a boring mid-day shot.
Anyway, I'm trying to sync up G+ to my blog and will probably be sporadically posting over the next couple days here on my blog. Please pardon the interruptions.
