nice! That's a bucket list of mine, even though I don't love bluegrass.
Ever say that to a big Billy Strings fan? They're like music Jehovah's witnesses. They will not stop trying to convince you he's the second coming and that you must love him.
Billy is very talented, but his band is really no different to me than Yonder, Greensky or any other new / jam grass that came before him. I "like" Billy, just like I "like" most bluegrass. I can enjoy it for an hour or two. But just like I can't do a reggae festival, I can't do a bluegrass festival. It all starts to sound the same to me after an hour or two.
