A most amusing moment occurred then, as the local 'Green Tortoise' van to Stratford was trying to make its way through the crowd and the luxury cars, the quintessential 'contrast' if ever! Posters on the Rick Steves forum took me to task for having simply recounted what we'd been told by local drivers: some of the volunteer Green Tortoise drivers are seniors whose sight is not as acute as it once was. So some locals wonder whether to pull off the road as the van approaches on dark country lanes.
