A small camoflaged container - you will need to bring a pen.
If you do this cache in an easterly direction from Market Harborough, you will bear off the main road up to Stoke. Once you have found the cache and you wish to continue towards Corby you will then need to continue through Stoke and Wilbarston to pick up the A427 again at the other side of Wilbarston. If you wish to return to MH, then go down the hill and turn right at the White Horse Inn in Stoke and then you will find a slip road back on to the A427 under the By-pass bridge.
If you do this in a Westerly direction from Corby, you cannot turn right onto this road near ground zero. Instead turn right into Wilbarston much earlier and follow the road all the way through to Stoke Albany and to the end of the old road.
DO NOT attempt to drive onto the A427 from this cache location passed the NO ENTRY signs.
