This cache is placed by Team CDI (Royal British Legion) whose members use this underpass every work day, usually around lunchtime, when transiting from the office to Eastleigh town centre and back. They will be instantly recognisable due to their happy smiley faces that are always worn 24/7.

You will be looking for a magnetic nano, so please bring a scribbling stick with you and beware... This is a very muggle-rich environment, coming at you from all directions with motor-muggles waiting at traffic lights, or parking their muggle-mobiles, only a few metres away - STEALTH is the key here. The difficulty rating of 2 is to recognise the Stealth Factor for what is otherwise a relatively simple find.
