The autumn has officially arrived to Antwerp, therefore the three of us decided to go outside and explore the beautiful park, Rivierenhof, next to the education center. Our field trip resulted in some great pictures of the colourful nature, a lost (but later found) cellphone and a little message to everybody who walks by a field in the park. Cover up – a message for everybody who wants to stay healthy this fall. Cover up (a.k.a. put on clothes) so you won’t get a cold now when the temperature is getting closer to the freezing point, but most important – cover up so you don’t get HIV.
