Which might allow us to camp over,it's a good pub too:
The Breakspear Arms, Breakspear Road South, Harefield, Uxbridge UB9 6LT
Probably a better location than the campsite I posted,no facilities once the pub's closed for the night but camping may be free and it's a 15 minute ride from the Ace-let me know if you want me to investigate,I know the bike club that meet there.
