Just wondering what the Burnaby Mountain/SFU trails are like. We are looking for cross-country trails, as our old bodies are a bit banged up lately from the North Shore trails, and we need a little break. Is it worth going up? We're happy to ride up if need be. Oh hell, if it is a little "shore-ish", we definitely won't complain. Can we get a 2-3 hour ride in? And, has development chewed up the area?
