The cache is situated within a few feet of a parking space, on a small lane. From M42 J4, head towards Henley (A3400) and take first left at the traffic lights into Gate Lane. The cache is about half way along this lane (i.e. only about 0.5 mile from J4), and there is a parking space for 1 car either side of the cache. The lane can be very busy - it is used as a short cut to get to the motorway - and is quite narrow in places. Watch out with little ones. Remember how you retrieve the cache - it goes back the same way!
The cache is intended to be used as a TB exchange point as well as for other swaps. It is a 3L tupperware type container, so there should be 'plenty of room at the Inn' for TBs. Please swap TBs - only take one without leaving one if you can really help the TB towards its goal.
When this cache was first published, it was used as an experiment to see how variable the co-ordinates were for various GPSrs. Thanks to the 26 cachers who have provided a waymark. Below are the results. Click on the image below to see more detail. Looks like Etrex GPSr is the most variable!
