FYI- I’m looking for 4 Saturday Rockygrass passes. I was contacted by “Jake” in the forum chat shortly after posting my In Search Of request. He wanted to do transfers by mail. I called Planet Bluegrass to be safe. They said they can do a 3 way call with the parties to facilitate the transfer. They fill out the transfer form and submit it after the payment has been made. This protects buyer and seller.
I replied to “Jake” that I wanted to use this method. He said that deadline has passed. I told him that we have until June 14th to use this method. There was no reply for about an hour. I came back to check our chat, and he had deleted his forum account. Happy that I didn’t get scammed, but sad I can’t find Saturday passes. 
Make sure to use the call in method for all purchases and transfers!
