Supposedly I have always had access to that as part of my USI subscription but have never once been able to get it to work. I suppose I could try again. Have you ever had any luck logging onto USI Wifi outside?

ETA: Nope. As always, total fail. I can see "City of Mpls Wireless" on my phone but cannot connect to it (tells me signal is too weak, "move closer."). iPad was actually able to connect, but connection was weak and unstable and essentially not usable.
