Greenbush is a municiple airfield in Minnesota with 2 grass airstrips. I have converted these to 2 ashphalt strips giving a good choice of direction for take offs and landings. I have also added a helicopter landing pad in a suitable position for easy approaches and to take off from the helipad (V1.1) select E for east departure and W for west departure. The airport elevation is 1000ft with flat terrain. Suitable for small to mid size GA aircraft.
