We can certainly change the OB on 15 if the majority feels it is unfair to have to throw the approx 215' across the trail. Of course one could always throw to the right of the trail (due east off the tee) to advoid OB. If we call it not OB, then it won't be OB further up the hole either.
As you know, I'm all for OB. However, try to implement it in a fair manner. On hole #15, a high percentage of players can make it across that path without much problem. So why punish those that can't make it or sometimes barely make it with their longest throws? It's like taxing the poor and leaving the rich alone. Playing off to the right is still a built in extra stroke. If you want to add OB on that hole, my suggesting would be to designate any tall grass/brush to the east of the path as OB. Only the mowed grass would be in bounds. That way the rich have to deal with OB considerations from the tee, not just grip it and rip it. The poor then have to deal with the OB, to a lessor extent, on their up shot.
But like bob said, your league, run it as you see fit.
It's not "my league", it's a rogue league and this particular OB question will be discussed and perhaps voted on by those in attendance Monday. All I do is collect the money, pay out the winners, keep the ACE fund secure, try to have a light supply, shovel snow off the tee boxes, annonce which tees to use, and call out the OB, (which has been discussed with the core group) and try to help all my DG friends have a little escape and fun.
