Went and checked out Backfire. Some nice folks, some great bikes (several SOHC 4s in great shape that put my ratty 550 to shame, Daytona RD400, mint KZ1000, a beautiful Triton and quite a few other old Brit bikes) and more than a few monstrosities. Todd, one of the organizers, has said that the number of "club affiliates" has been on the rise and I could certainly see that. But it's also cool to have an event where pretty much everyone is welcome, from 49cc mopeds to bagger hogs.
I went to the Sunset at 6 to get a ticket for the show, but it was sold out. I've seen Guitar Wolf a couple times, so I wasn't that bummed, especially since a buddy had just texted me to tell me his band (Banquet) was playing at the Kraken, so that's what I did.
I'm gonna miss this weather when I head back to Phoenix...
