Yep, I know that "Purple Haze" was a Jimi Hendrix, not a Grateful Dead tune; but Bear likes the bear so much that he made it an emblem on his 1997 Harley Davidson Electra Glide Ultra Classic (aka, FLHTCUI). And he likes the song Purple Haze so much that that's what he named his purple and grey bike. And I like Bear so much that I'm having a set of these chips made for his birthday as a surprise to him.
