This is a slight deviation from the Wavendon Expansion area as we have strayed into Magna Park but it is very close by. You are looking for a small box with room for very small swaps and TBs.
Anyone doing our Adventure Lab "Wavendon - Old and New", will find that at this location they are able to complete one of the stages.
There are busy roads nearby so please be careful with children and dogs.
Please bring a pen and replace as found i.e. well hidden.
