When Flying into these Active Museums a little bit of extra care needs to be taken as the locals do tend to operate slightly differently and have different needs to the average GA jockey, eg PA28s don't tend to need to do Run & Breaks!
However, it is great fun to mix it with the interesting stuff, and yes I have had a Harvard run & Break next to me as I am touching down, and had an AirCobra push in at the hold for take-off, but I love the atmosphere and experience of flying into Duxford and Old Warden
