I've got two locks, too, and will be putting my trike straight in the car at Castle Hedingham so both would be available there. I'll be using one/both of them at the Dolphin.
I think I went almost two whole days in Germany without locking up the trike at all. Most of the time I only locked it as I had the locks anyway and thought I might as well use 'em. It's a bit different in Good Old Blighty though.
Also, if/when England get knocked out of the World Cup, do I need to remove my England flag straight away from the trike? I'd have to find where I've put the orange one. And, of course, I'd still be retaining the German flag on it...
