Middle notes: "There will be no water provided on the course or
at the arena." "Please bring lots of water as none will be available."
May I assume you got a waiver from Orienteering Canada for a deviation from
Rule 6.8.1?
(I plan to have a Camelbak with me, but wanted to highlight this note for others packing for the event.)
[Edited to add:] The other courses also list "no water" in the Arena, but presumably are close to other water sources such as drinking fountains.
The Middle requires a bus ride and walk. Be prepared!
