(Will Shilling photo) Those wanting to learn the art of backpacking should definitely check out this four-part class at Columbus Outdoor Pursuits. For less than $100, you'll get hands-on training on every part of the sport. Yesterday, I stumbled upon another great Ohio nature blog kept by Tom Arbour, an amazing photographer who lives in Worthington. His bird shots are out of this world. Columbus Audubon is taking a field trip to Killdeer Plains to spot winter waterfowl on Sunday, March 1. Groups will carpool from the Worthington Mall parking lot at 11:30 a.m. Also, your 2008 fishing license expires Feb. 28. You can renew it online here.
