No way I can join you, but I would if I could! Peter is a great guide, too, and a day out on his turf will be a day well spent. I especially recommend Bective Abby -- early in the morning, with the mist rising off the river, is not to be missed! But it's good any time.
If you don't take Peter up on his offer, you'll regret it! I did and I have a couple of "wall hangers" to show for it!
