Lost on Burnap's Island

Not familiar with posting here. This is my second attempt, so please forgive me if this is a repeat. I lost the rainfly to my REI Passage 2 green tent on the beach at the south end of Burnap's Island. Left it there the morning of August 18 while breaking camp. Laid it on top of some vegetation while breaking down the tent. Don't normally do that, but I was a bit tired after paddling 185 miles in 6 days. Anyway, if anyone finds it, please let me know. My tent is only have what it once was (and not of much use in the east) without it. Thanks in advance for any help anyone can offer.
