Bob and Denise are caravaners
. In other words, they live in a caravan as they drive around the country. But they resent the way non-caravanners treat them. For instance, the way people in flashy sports cars sometimes make rude gestures as they speed by their caravan on the road. So Bob and Denise are organizing a campaign "to secure equality and respect for caravanners." They're hoping to mastermind a 'ring of aluminum' that will circle London on June 5th, created by thousands of caravanners going slow as they drive along the M25 that circles London. That's all well and good, but something smells fishy about Bob and Denise. They're just a little too offbeat and cutesy for their own good. Could they possibly be the creation of an advertising agency, along the lines of the recently seen Travelocity Gnome?
