I have learned the following lessons after a lot of stupid mistakes, and days like the one you so humbly related to us.
1. in the winter I carry at least on bota bag for water and I cerry it under my coat, I guess a camel back would work too.
2. My compass has never frozen up
3. Sorrel boots are great.
4. put your scoped weapons in your truck the day before or at least several hours before you go hunting and when you transport it keep it in the back of your truck that way it's already a the air temp.
4. dry grass is easier to light if you roll it between your hands, and use your plastic garbage bag to shelter your fire pit while you start it.
5. tell your wife that you were wet and it got so cold that when you brushed somthing out of yor hair it broke off.
6. even with lots of training and practice you will still have days like this one.
Just remember that as humbling as the day was, a bad day in the woods hunting is better than a good day at work
