Duster,
Born and raised in Maniwaki, I've been sledding the area for years. It's my playground. I hear ya to be preoccupied with security. If I can reassure you, I have never ever heard or read in the local paper of a sled/rigs being stolen neither at Auberge du Draveur nor at the Chateau Logue. Guys from Syracuse always leave from Auberge du Draveur on their annual saddlebag trip. It is a small community and lots of people are choosing Maniwaki as a starting point.
That doesn't mean not to lock up your sleds at night. We always do when saddlebagging.
Hope that helps.
