From this UPDATE dump, this parser helps quite a bit to decode what is going on: http://bgpaste.convergence.cx/
Looks like the AS_PATH was 0 bytes long, which is invalid and Frank's router did the only thing it knows to do on BGP errors - drop the session. Further from the decode: The NEXT_HOP was 206.108.255.89 And the Routes were 204.73.77.0/24, 162.255.252.0/22 and 0.0.0.0/0 Looks like Minnesota WiFi should check on their route announcements.
