I plan on coming to the event on the 26th and I would like to bring my dog next time I go to Tucson so my new roommates can meet him, but I don't want to leave him alone at the house before they even meet. So I was wondering if SIR would care if I brought a dog on site (I'd clean up of course), and if there is any good shady spots I'd be able to tether him to.

Shouldn't be a problem. I know Kenny used to bring his dog, and I've always seen a few dogs with spectators on the occasion.
I love dogs
