Blackall Preserve in Cumberland. I go by here on my way to work and I've been waiting for it to open. Please follow the red trail. The terrain varies from easy to somewhat hilly. A good all around workout. Some spots are muddy and some are flooded but you can get through. I'm sure some boy scout projects will be going on in the future. Typical old school hide. Use your geosense. Just a bit off the trail.
