As someone previously mentioned, Macclesfield Forest is a magical place at night - I remember bivvying on top of Shutlingsloe for a meteor shower and being treated by a light show in the sky and owls ghosting across the moor below me into the woodland at about three in the morning.
As a Volunteer for the National Park its often tricky reconciling wild camping with the bye-laws etc, but I try and pitch late, leave early - I only use a stove rather than setting a fire and any rubbish I carry out.
