I had to get up in the night to check on the bike as it was parked on dirt... As it rained heavily for a few hours. In the end it was pitch dark and I had two disc locks to get off, then I could see f.a. and took it down outside the main entrance.
When I came to shift it later in daylight, I found I was only about 2ft from nice firm tarmac! Bugger!
Today is boat trip day, 1020 from St Goar. Let's see how it turns out.
