Here's an idea for those of us who like to stay warm on those cold hunting days. Take a roll of toliet paper and soak it with rubbing alcohol. Put it in a metal coffee can and light it. It usually burns 4-6 hours before it needs to be replaced. The toliet paper never really turns brown, it's just the alcohol that burns off. It does'nt smell either. I've used this method several times and was wondering if anyone else has ever tried it.
