ah ! fair point, I wondered if it might be something like that...thing is junkie's would nick 'owt if desperate enough ,if it could be sold, i'd keep the bike in the house....good luck..
(I don't think it's a bad assumption, I got my current bike just before I moved house, and I had similar concerns about my nice new bike, which was 'sick' in current young 'uns parlance, the attention just made me nervous, any way nothing happened and where I now live that kind of threat is a long way off)
