TTT stands for Team Twitter Trail. The trail came into being after a discussion between local geocachers over Twitter. The Team Twitter Trail is a trail of caches around the Peterborough Green Wheel cycle network. Caches are placed at regular intervals along 50 miles of cycleways, footpaths and bridleways that circle the city of Peterborough and surrounding villages. Each section of the trail has been placed by a different member of the team and reflects their own hiding styles.
"Geographically embarrassed" is a euphemism we heard for "lost" on the radio recently, and it also strikes us as quite an apt description for this cache - basically we placed this cache for this trail and realised it's actually slightly off the trail! Oh well, we've done it now, enjoy 
Take care with geokids close to bridge. Cache is on level safe ground, and there is no need to go near the water.
The cache is not accessible using fingers alone, as it's cunningly secreted in a small hidey hole. There is a small magnetic attachment on the lid. Please bring a magnet with you no more than half an inch in diameter, (on the end of something such as a piece of string) and you will be able to use it to attract the cache.
