If you were ever interested in riding the Duffy Lake road, you could get there without having to come into Vancouver.
You could ride to Nanaimo and get the ferry to Horseshoe Bay. You are right beside the Squamish highway there and you could ride to Pemberton and to Duffy Lake and Lillooet from there.
Then you could come back down the canyon and you could get to the ferries via highway 10. You wouldn't have to go into Vancouver at all.

Or you could do the reverse. Start with the canyon and finish at Horseshoe bay.
