Muggles are a big problem here at nearly all times of the day. Please take excellent precautions when searching, finding, signing, and rehiding to ensure a long life for this cache. You are looking for a small blue plastic container, and will need to bring your own pen! Please rehide exactly as found, and note in your comments if the log gets full, as we have local contacts who can replace the log if needed.
We tried to place this in the most 'out of sight' area of the park, but you'll still need to take care. For your own safety, strongly suggest not attempting this one at night.
