You turn your bike round, buy a posh coffee, collect the caches, and move on.
There isn’t much to say except that all the above activities were achieved with a minimum of fuss. The main danger was overlooking by other punters. Both are in prominent locations. The two caches there are called M6 Sandbach Services Southbound and Motorway Mayhem M6 Sandbach Services Northbound , and both are by The Bignall Boppers.
Hopefully the photo sums it up.
