...The unplayable lie may be relocated to a new lie that is: (1) No closer to the hole, on the line of play and within five meters of the unplayable lie; or (2) The previous lie...
The line of play referred to here is that between the marker denoting the lie deemed unplayable and the target?
Left hand side of the fairway up near the basket had a very steep drop-off covered in thick brush. My disc was located about 5' off the fairway but 8' or so below the level of the fairway. It was difficult to maintain position on the slope without sliding and there was no room for a throwing motion, much less an opening to throw through, so I called the lie unplayable. I checked with my group and moved my lie laterally onto the fairway, much as one would do with OB, and finished the hole from there. Being a little uncertain I had played this correctly, I checked in with the TD and a couple of the more experienced players and they confirmed my play but now I'm not so certain. Assuming the answer to the question with which I started this post is "yes", the only option I would have had was that of previous lie (re-tee in this case) as any lie behind the lie deemed unplayable simply was not possible, placing me further into the mess downslope. My lateral relocation was illegal?
Considering the round in question was my worst rated round to date, I'm not particularly concerned about what has happened, I just want to avoid future mistakes.
