I guess I just disagree with you guys on this hole;
Chuck, you are right about OB needing to be totally enclosed, except in this case, where the mando clearly defines the end of the OB line. There is no question about being in bounds or out of bounds on this hole. The ONLY question on this hole is; Where is the line that defines making it past the wrong side of the mando, or simply being out of bounds. Once past the Mando, the OB disappears.
Now there is another hole at Steilly that has a very poorly marked "ending" to the OB line and that is hole SE14. This is a case of the OB needing to be clearly marked all the way around like a water hazard.
