A regular upwrong tandem could probably be manouvered through the pedestrian gates at the Hampton Hill & Kingston sides of Bushy Park by sitting it up on its back wheel.
Unfortunately our recumbent tandem trike is too heavy and awkward to do this with (OK, I managed it once, but nearly ruptured myself doing it), so we have to use the road gates. Which is annoying, given how close we live to the Hampton Hill entrance to the park.
