Hyvinkää Paavola school yard has old gym house. The tall wall nearest Väinölänpolku is legal for everyone to paint - no permit needed. Other sides are murals made by artist and local kids, don't paint over! Maybe 20 meters wide and 5 meters tall. The wall has wooden paneling but ok to paint. End of Oraskatu has free parking lot for cars.
Is this wall still safe to paint?
