I would love to see all tobacco products banned from golf courses, in general. Cigars are the worse. The smell is awful, even after the smoker has left. The smokers leave them everywhere and who is supposed to pick them up? Disgusting.
Understand why this will never happen, but at most should be treated like a dog. Clean up after yourself. Douse the cigar with water and put it in a bag. Or designated smokers cart with ash trays. Oh sure, that will happen...
