My GF and I will be traveling from S. California for a couple of weeks, including a 3-4 day stay in downtown Portland. We'll have bikes with us and would consider using them to get around the city. Is this a good idea, or is walking/public transit easier? In general, how safe are locked bikes? GF has a GT flat-bar road bike, and I'd probably take my old Stumpjumper Pro or my CX. Not high-dollar bikes, but not $50 beaters either.
