The tweet above ^---^ was replied to by someone from Saltspring Air, a floatplane service that flies from downtown Vancouver to beautiful Saltspring Island. I speculate they may be going somewhere by floatplane.
Hey everybody! I'm a longtime lurker here but huge fan of The Amazing Race.
I visited Jack Poole Plaza yesterday and Salt Spring Island Air is located just west of the cauldron.
If they are heading to Salt Spring Island, here is the departure info from Downtown Vancouver to Salt Spring Island:
Departure: 8:45am / 11:20am / 3:25am
Arrival: 9:25am / 12pm / 4:05pm
The website also has planes heading to Maple Bay, Pat Bay, and Gulf Islands that transfer or stop at Salt Spring Island.
These arrive at: 9:50am / 12:25pm / 4:30pm
