RE: What would you do?
Guess I'm lucky. Our club has 6 3-sided chain link fence enclosures (open to the back) with the top bar being about 4 ft. high. Plenty of room for 3 people side-by-side uncrowded. These have saved many from aborted take-offs, poor ground control and out of control flying.
Do your homework and cost out the pieces. At your next club meeting put a work proposal to improve the safety of your field. Maybe the AMA can provide some help.
