A272, absolutey, but don't forget the B3049 from Winchester to Stockbridge. This was originally the A272 before it was down graded and has the A272's "character"
Ooh, I love that "old A272." My folks live in the Wallops, and when I was still living with them I used to have a girlfriend in Winchester. Late night returns homewards on the section from Sparsholt up across Stockbridge Down, down through the village, then turning off the rise out of Stockbridge to sweep past Danebury and past the back of the airbase. One of my very favourite drives, which almost made coming home from the GF's house worthwhile

Where I am now, in the southwestern outer suburbs of Toronto, there are very few really good drives. Too many of the roads are old lot lines and concession roads, all based on 19th century military surveys, so they're all straight lines and right-angles, and out in the sticks can all blend into one unmemorable lattice, being numbered consecutively from south to north or from west to east. Added to which there are usually unfeasibly low speed limits and stop signs at all the corners
However, there are one or two good jaunts around the Niagara Escarpment, where roads tend to have the "proper" combination of sweeping bends and undulating straights, and even a hairpin or two. My favourite route has some good local names, too: take Guelph Line past Mount Nemo and through Lowville, then Appleby Line up to Rattlesnake Point, pick up Nassagaweya 5th or 6th Line to #15 Sideroad, cross the Nassagaweya-Esquesing Townline (try saying that after an evening in the pub

), and return home through the more prosaically-named Georgetown and Milton to Oakville.
