0 Guest Posted July 31, 2008 Report Share Posted July 31, 2008 Should trees be equidistant from each other in all rows? Or, gaps between trees can vary from row to row? And also are we looking for a solution with minimum number of trees? Quote Link to comment Share on other sites More sharing options...
