On the A20 in France, going north bound, we saw a Harley type mobike, south bound, towing a small 2-wheeled trailer. The sole content of the trailer was a beer barrel, like a barrel with wheels. It was a highly polished and immaculate barrel. So, was it full of beer? Or was it full of food and clothing? I shall never know! If the latter, it would at least be waterproof. And ingenious.
