This cache is placed at the Bancroft Tower, a real-life castle here in Worcseter! I recently discovered this place and knew that it was a perfect spot for my first hide in town. Parking is availble right next to the tower and the cache should be easy. Please don't find it at night (the park is closed between 8 pm and 5 am) and bring your own writing utencil. You can also see a slight view of the Woo on each side of the castle.
