Geocaching is a great way to find new interesting places - no matter if you are near to your home, on holiday or on a business trip. You can do it alone, or with all your friends. During day or night. On a mountain top or under the water. Solve tricky puzzles at home or simply go out and get "some".
Bicycle riding
Riding my bike is to me pure relaxation. Fresh air and fast enough to get around a little and discover interesting places.
The best way to perk up the tired bones after another long day in the office. You get more agile and feel a lot better - at least after the exercises.
The greatest happiness on earth is sitting in the saddle of a horse. Everything said!
OpenStreetMap is a collaborative project to create a free editable map of the world. I like contributing in many ways, be it by collecting data during bicycle tours, road trips or when on holiday, writing documentation or developing some editing support. I'm also a member of the OpenStreetMap Foundation.
