Looking for something to do this weekend? Head out to Colonel Denning State Park and go swimming in their 3.5-acre lake. If you are feeling up to a challenge hike Flat Rock Trail (trail head is in the park), it is a 2.5 mile (one way) rocky, vertical climb. It's not easy but once you get to the top to the 180-degree view of the valley, it will all be worth it. Be sure to pack water and a light snack (I had trail mix). There are also a selection of easier trails if you are looking for a leisurely hike. Be sure to download the brochure and map before you go - http://bit.ly/byep4U.
