Everyone is raving about the new PBS documentary series by Ken Burns. Full episodes of The National Parks: America's Best Idea -- along with cool extras -- are available here. Earlier today, two Ohio state senators introduced a bill that would establish a safe lateral passing distance of three feet when a motor vehicle passes a bicycle or other non-motorized vehicle. As an avid biker, I think this is a great idea. Organizers of the inimitable Doo-Dah Parade will host Urban Croquet at noon Saturday, Oct. 25, in the Short North. If you've never played, it's great. Don't forget to check regular updates on fall color here. I'll have my favorite spots in this week's Venture.
