Ey Oop Bumblebee,
Welcome to the club! (bit late but hey ho)
I'm just down the road from you and know the A14 round here well. Only issues I've come across are the traffic (obviously) and the damn roadworks going on both north and south of Brampton Hut roundabout (A1/A14 Huntingdon). BTW careful going round that, they come at you from all sides and I've nearly come a cropper twice accelerating away and going over a patch of oil or petrol - your back end swings out from under you.
Talking Bikesafe, they do it at Huntingdon, I've booked in for the first one this year in April, google it, dead easy.
I went to NVM last year, am down for it this year, and I have never met such a motley bunch of drunkard ne'er do wells before..... and therefore a cracking weekend!
Go if you can. If you fancy a ride out sometime, shout!
