One of my most favorite things about living in SF was living across the street from Golden Gate Park. I'd take a lot of walks and I always ended up a the dahlia garden when they were blooming and the other day I had a break in between gigs and stopped by. The dahlias were certainly in bloom and I saw some that I've never seen before! Damn, I love this flower, enjoy!
If you have never been there before, just go to the Conservatory of Flowers and look over to the right hand side. I love this spot, so take advantage of it ASAP!
