Behind my parents house there is a park.
When it has rained, like it does at this moment often in Belgium, even though its August, I go running on the soft wet forest tracks in the parks forest. Its the best time to go jogging. The air is moist but fresh and full of oxygen the track is soft, there is no dust and normally there is nobody around except for the animals of the forest.
This is ideal to think, set the mind, have ideas and above all breath and feel alive!
