This is one of 15 simple geocaches in a circular route set out to coincide with my 'Yorkypudding's 15th Birthday' event (GC8H3TY) which takes place on Saturday 15th February 2020, fifteen years after Yorkypudding's first geocache find, and forms part of a walk of approximately 3.6km on mostly steady terrain that should help attendees build up an appetite (and/or a thirst) on the day and won't be too challenging for others walking the circuit at a later date.
From WP15:06, just continue along the path, with industrial buildings behind the fence on your left, and the river below on the right.
This cache is where the view to your right opens up and you can see Boston Castle up on the hillside opposite (and a certain fried-chicken outlet rather nearer on the other side of the river!). Mind the brambles.
You are looking for a micro in a camo bag.
