Hi John,
Congratulations on becoming a Freeman. You'll have to wait until next September to exercise your right to drive sheep across London Bridge.
Two tips to remember: 1. Book your sheep as soon as the website opens and 2.don't let the sheep jump over the bridge!
It's a great day out and well worth it just for the looks on the faces of the tourists! Walking sheep on the bridge? On a Sunday?? Quaint people these English.
