I've got a new app that's called OsmAnd (Open Street Map Android). I've got it primarily for my trip to Greece because the old OSM app has become buggy. A very nice feature is that it displays places of interest including some from Wikipedia and that's how I discovered the bicycle museum at Walton Gardens.
Obviously, it was shut, so I had to take this photo through the window, but I wouldn't have discovered it without the app.
Just incase you are wondering, I've recently added a half mile extra to my walk by making a detour through Walton Gardens.
