I just noticed when this year's Linux in the Park is, and thought that I should pre-warn everyone about some routing issues surrounding July 23. Bloor will be closed between Lansdowne and Dufferin on July 23 (and 24) for the Big on Bloor Festival of Arts & Culture (http://bigonbloorfestival.com). As you might expect, Dufferin Station will correspondingly be busier than usual, and parking may be harder to find. College streetcars may be busses, and may also be affected by streetscaping-in-progress.
