Hi Failbender.
That is 100% a reference to your brother. I was wondering if anyone would ever catch it! I used to play festivals like Rock the Resort (hence, Rock the Warehouse) and Strange Creek in a few different bands, most notably Neighborhood Formula and Positive Mental Trip. (I even played a guest spot at silent disco at Vibes one year.) I also followed the Dead on tour back in 2009 when they had Warren, followed Furthur for a bit as well. I mean I also listen to heavy metal, synthwave, and hip hop among many other things, so I'm not 100% hippie Deadhead. But I've gone to / played dozens of festies and gigs in the jam band circuit.
I've seen Mr B's festival needs everywhere. Gotten supplies from them, hung out with girls who said "I got in for free, I volunteered with Mr B's festival needs and got a free wristband!" Mr B's rocks it, that's why I felt compelled to make a reference, in-game, given his service to all the hungry hungry hippies over the years.
But yea, good eye, you caught the reference! Tell Mr B's he rocks
Cheers,
Jon of the Shred
