BBQ
The conference “banquet” will be a barbecue in nearby Waterloo Park, on Wednesday August 14 from 6-8pm, at Picnic Shelter #20.
It is approximately a 20 minutes walk from the conference location. A group will be walking over to the park, leaving from the Davis Centre (DC) 1301 room at 5:30. If you have mobility requirements, please contact the conference chairs to make arrangements to get to the park. The exact latitude and longitude of the picnic shelter is 43.465222, -80.536528.
In the event of inclement weather, the barbecue will be relocated to our backup rain location, the Math 3 (M3) atrium, on campus. An announcement will be made during the day at the conference if we are relocating.
