Hobbit
Great idea! You won't regret it. I flew a SuperCub for a couple of years and loved every minute of it.
You don't mention Popham, presumable since that's so close to OS as to be obvious.
If you fancy dropping into a nice farm strip, Keyston is hard to beat (just south of Alconbury on the other side of the A-14), and if you're going up as far as Duxford, it's not a million miles away.
Enjoy the trip!
