We arrived on Wednesday 14th at midday, the noise from helicopters very loud as testing and flying going on, no real problem as daytime. That night despite a strong lock, our expensive bike stolen, also neighbours expensive locked bike taken. Wardens very helpful and police contacted. Police visited us next day to take details and very surprisingly they were able to return the bike the following day as it had been dumped in a layby. Luckily I had put chain through the front wheel so thieves were unable to wheel it away and needed to carry the bike, I don't think we would have got it back otherwise. Hats off to Police service for very efficient help as we were leaving early next morning. Also disappointing that the last bus returns from Uxbridge to Denham at 2.15pm so a taxi needs to be taken from Uxbridge (cost approx. £15). Tried phoning to get a taxi from Denham station but 3 firms refused as too busy (7pm), its a long walk up that hill after a day in London. This site is not for us.
