Wearing my other hat, and with much input from other members of the Dalhousie Community Association board, the DCA sent two letters. One to the Marie Lemay of the NCC regarding the bad idea for bringing Rapibus to Ottawa over the POW bridge; and the other is detailed comments on the current state of the Downtown Ottawa Transit Tunnel study.
