Well , strictly speaking , he hasn't done the whole of the Thames.
He stopped 200 yards short of the lock yesterday , and started 100 yards downstream of the lock today , so there is a stretch of water 300 yards long in Teddington that is unswum.
We should start a Facebook campaign to get him to come back and finish the job i reckon
P.S. can a mod resize those photos , it's difficult to navigate the page.
