I can vouche for Grey Gables. Maybe not quite within 2 hours of M'boro, but a great B&B (actually, D&B&B -- they also serve dinner). Great food. Hilly but beautiful country. When Dorothy and I stayed there a few months ago the owner mentioned that she'd like to have some bike routes to offer her guests. She emailed me a general description of three routes and I worked up cue sheets and maps for her.
