Hi Dave,
You're right about there being a mountain of information available here.
I subscribe to a forum for Moulton owners and they have a weekend get together every year at Bradford on Avon. They camp in the grounds of Dr. Moulton's stately pile and have bring and buy/swap stalls, local rides and a dinner, amongst other activities. I have never been to one but it sounds terrific.
It's probably a daft idea but wouldn't a Thorn weekend be worth considering?
We could talk for hours and swap ideas about Ripio sizing, Rohloff vs Campag Super Record, how to carry 45 KG's of essential touring equipment over the Andes and PBP on a Raven.
Just a thought......
