I drive regularly to Galway and have a love/hate relationship with the M6. It has certainly saved me a lot of time but I find it soooo boring. On top of that there aren't many geocaches along the route. As a result I decided to set up a series along it to provide drivers with a break and to make the journey a bit more interesting. None of the hides will be particularly difficult or exciting but at least you can stretch your legs. There will be no room for swaps.
This is absolutely my favourite junction on the M6. I won't say why but the reason is across the road from the cache.
You are looking for a micro hanging on the fence.
This used to be Time For A Break - Junction 16 but I love the SideTracked series so I changed the name.
