Portland has good beer. There, now I've said it. One of the key benefits of holding the RailsConf 2007 conference in Portland has to be easily obtaining really good beer.
The McMenamins on Broadway is the closest place to the convention center to go where "Classics such as raspberry-tinged Ruby, medium-bodied Hammerhead and dark, strong Terminator Stout are always available."
In between the fun of learning all about Rails 2.0, Capistrano 2.0, scalability, more scalability, still more scalability, let us not forget to take the time to drink a really good beer together! Or more than one, perhaps...
Update: It's official...here is the link for RailsConf on Beer
