I normally never start a fire on backpacking trips but I do carry storm matches and feel that I could, in most situations, start a fire under emergency conditions. However, on my upcoming Foothills trail thru hike, I'm thinking that the long winter nights, abundant fuel and many established campsites with existing fire rings might make a campfire attractive on one or more nights. I'm thinking of using vaseline and cotton balls to make a lightweight fire starter kit. Is this the best solution? Any insight from folks who do lots of winter camping would be great.
