I am with wapiti. I used to live in burquitlam and I am curious about what route.
Cariboo Hill? That would make sense. That was starting hill every morning coming from Gaglardi and Broadway, it was a great warm up to a 15 mile ride. Then on the way home I had Byrne road halfway home. But river route you posted was my normal route, it is nice along there. Though it has been years.
