I was in your neck of the woods yesterday on my Challenge Seiran after riding the NCN 74 from Glasgow to Carlisle. Arriving in Carlisle for the evening rush hour and trying to find my way to the station was a bit dicey.
Anyway I live in Newcastle so most of my riding takes place in eastern Northumberland or if its mid week up where I work around Dumbartonshire/Argile. Mrs B is also laidback on an ICE trike.
I bet the Fujin will be a rapid machine, though life is pretty hectic for me at the moment I'm sure we'll meet on a ride at some point, its always good to get out with other bents.
