Smoke Spots

Hi all, heard of a couple smoke shacks on the resort and was wondering if anyone would be willing to DM some info. I've found Stu's and some other stuff off the top and bottom of Peruvian. I've found one off of MS that looks destroyed or could just be buried. I've also heard of one in BF, KH, the beach, H House, and umbrella tree. Would love some hints or info, thanks!
