I would even suggest taking this one step further and consider designating other OB lines, when warranted, with this special condition.
The concept definitely works in other situations. I think it would also be better on hole 3 at the USDGC than the retee that was done last year. Although, I think using a drop zone across the road with the normal 1-shot penalty would also have been better than a forced retee. Six of one, half dozen of the other.
