Phat,
I think you experience would be invaluable, especially with winter camping. In a lot of areas, winter camping is not encouraged. I know that if I lived in snow country, I would love to learn to camp in winter.

If you register as an "adult leader" with the council, then you can offer specific skills to all the troops in the council. This way you don't have to be tied into just one group and be responsible for more than what you want to do.

Although I am an ASM with a troop, I offer my expertise in teaching First Aid and Backpacking (light weight!) to all the troops in our council.

I'm not sure how things work in Canada, but I'm sure the principle is the same.
