Great suggestion....I would nominate Jacob for a lecture on photography.
If someone is skilled at bear bagging, specifically, the PCT method of bear bagging, that would be great to see.
I would consider giving a small talk on fire starting using a fire steel and three methods of using a cotton ball as a form of tinder to get a fire going.
Also, I would nominate Cameron to talk about gourmet cooking on the trail....talking about what he does at home to prepare his meal and then how he prepares it in the field.
It would be cool to maybe have a contest to see the most creative tarp pitch, setup.
