update - leg/bike situation
Hello everyone, and thanks again for the suggestions and offers of help
I myself am back in the UK - I arrived home at 1:30 am this morning, after approximately 12 hours of travel (taxi to airport, flight to Heathrow, long drive home). It's nice to be back, though obviously I'm sad my trip was cut short.
My insurance were very good, they flew a friend out to take care/help me - there's no way I would have been able to manage all my bags on my own - and arranged for me to have 3 seats on the plane on my return journey.
As for the bike - god bless Auntie Carole!! Carole Nash give free European breakdown cover via the AA - this has a clause for recovering your vehicle if you are unable to drive. Obviously whether they do this depends on the value of your vehicle and how far from home you are. They decided it was economically worthwhile bringing mine back, so it was picked up a few days ago and should be back with me in a few weeks.
Next up: get my leg fit and well, so I can drive and ride again...
