For Montréal, we know at least about the tiers-lieux which consider themselves hackerspaces.
Shift-click Foulab, ECTO and Sensorica to open them to the right and add them to the lineup of pages. Then also shift-click All maps together.
Do so alike for other combinations of pages with maps. The ← left and → right arrow keys or clicking pages refocus the lineup view.
Then, we still know about the refreshing effect of green public urban space. Our friends from eco2fest invite to a temporary outdoor intervention at Parc Jarry 
, which is not too far from Koumbit.
