This is the most underused patch of rolling, perfectly groomed greenspace in Little Rock. It's the front yard of the Clinton Library and the side yard of the Clinton School for Public Service and it's been gently terraced in a way that makes you want to crawl into a sleeping bag and see how far you can roll down its slopes. There's wi-fi access here for folks who can't be parted from their laptops and a 2,000-foot promenade. An Arkansas River backwater along the park is being developed as the Bill Clark Presidential Park Wetlands, and though it won't really be a wetland, it will be a lovely place to walk and see great blue herons and marshy grasses. It will even have an educational component: Since it drains the city, much of the trash that folks throw in the streets makes it here; a collecting area will reveal it as a lesson in littering. Coming soon: The eastern link in the River Trail loop, when the $10 million project to turn the Rock Island Bridge into a pedestrian bridge is completed. Finally.
