Quick News Roundup

I've never done a news roundup before, but three things came across my radar today and I'm running short on time.  Explore at will:

• Anyone in the Portland area should check out Portland Afoot, a monthly guide to car-free and car-lite living.
• Villaraigosa's "30/10" plan to cram 30 years worth of regional transit projects into 10 years with the help of Federal loans is moving quickly, apparently! Great news for LA - let's hope SF's leaders are watching closely.
• A recent meta-analysis suggests that the intersection density of a city or neighborhood has the largest effect on its walkability.
