Indoor skatepark für BMX, Scooter, Skateboard, etc

Please let us help those kids who are into it, at the moment we have no place to go, no way to improvise, let us keep one whole sport alive in this country, in this city! My son is extremely into it, he is 9, and he makes a lot outside on the skate parks, still this can not replace an indoor place, he is making acrobatics on quads (4-weels roller-shoes) and so far he used Sport&Fun Halle, special area for this, now it is completely closed and removed! Tx!
