OK, I'm trusting that few locals are referring to this board for information (if they were, they wouldn't have been standing on the wrong side of the security fence around BC Place last night wondering how to get in). As such, I will share something, but please leave us a spot, because this is going to work well for me.
DH and I just went out for a drive into the Lake City area in Burnaby, which is served by the Lake City/University and Production Way Skytrain stations. Guess what? Lots of free street parking. No time limits, no signage about who can park there or for how long. Nothing. Several blocks of street parking within 5 minute walk of those two stations.
