Zip lines will reopen in the Hocking Hills starting March 28. Remember how much fun I had on them last year? Check out pricing and other info here. Those who want to make Columbus green space prettier on Earth Day, April 18-19, should check out Picture This. The citywide initiative is staffing more than 60 worksites around town. The Columbus Adventurers will head to Lake Hope State Park for camping and a trail clean-up April 3. Should be a fun, low-impact trip. [Info] (Will Shilling photo)
