Good for you Pete, things like this are needed to keep us sane. Anyway if you had a dog you would be allowed to go and walk it so what's the difference? Doing it your way was entirely responsible and thought out.
Mind you going for a 30 mile ride on a JAWA could push up the pollution figures again from all that two stroke oil! Only joking Pete.
Now to the serious business of which biscuits go well with a flask; I favour choc chip cookies. Lovely chocolateness and no melting. But for real ecstasy it has to be a cheese sandwich made with extra strong cheddar and fresh crusty bread.
Right where are my keys!
