"Btw, I noticed the Scout isn't on the approved container list. Is that an oversight?"
Probably, The scout is the newest one in the bearikade lineup. I recently aquired one and when applying for a permite I have only replied "I have a bearikade" to the question " do you have a bear proof canister?". They have never asked for the model.
The Scout uses the same end cap and lid and carbon fiber tube as used on the Weekender. The only difference is that the tube is cut a little shorter. So I would suspect the Scout is just as strong as the Weekender. The External size is also about the same as the bearvault 450 which is aproved.
