Jimr, don't know which way you'll come from Oxford, but if you come A420, theres got to be at least ten speed cameras between Kingston Bagpuise and Swindon (went that way sunday) And theres 2 on the A419 the streach that takes you to J15 M4. then go west to J16, unless you know Swindon, it's by far the easiest route. but then again you could come down the A34. Whatever.
