I usually camp at the Rugby Club( though not this year) and there has never been anything at the club on the first Friday night because the Rugby club is still being used by the regular club members. There is a bus which I think runs every half hour from the White Leys road round the back of the playing field although it is probably not running at the time you would want to return from the town ( but may be useful later?). If you walk back along Upgang Lane there are no hills, just turn left into Love Lane when you cross the old railway bridge and come out at the back of the playing field.
