A critical correction to some wrong information in the earlier post
on transit options.
Thanks to Kathryn for this vital news - "The 44 does not run on weekends!"
To get to UBC on Saturday, your best bet is the 99 along Broadway. If you're coming from downtown, you can catch the 98 south to Broadway and Granville and get the 99 west from from there. Go to www.translink.bc.ca to check out the route maps.
Again: Don't plan on the 44 on Saturday!
Apologies to all. I am ritualistically flogging myself as soon as I finish this post.
