My club is at about 5km from my home, 10 min drive trough town. Located at a military paracommando base, we have a 140m grass runway for our use (good short grass without bumps). About 5 turbine flyers at our club.
At about 20km there is a better known club, because every year they organise a well known international jetmeeting in belgium (jets over pampa). Haven't flown there yet, but hope to next year.
