Hmmm... I don't have 10 concerns, but here's what I do have...

1) Other people (I think the Ozarks have one of the highest percentages of people who hike without a clue)

2) A tree or big branch falling on me.

3) Falling and breaking a bone.

4) Twisting an ankle.

Of those four, only the first has happened, and it's mucked up more than a few trips.

That's about it. I finally gave up and started bringing "Taster's Choice" singles and they're light and small and cheap enough to bring plenty extra, so I don't worry about coffee as much anymore

Although not a concern, I do get a little disconcerted that I haven't stumbled upon any lost treasure or alien spaceships or any of that other cool stuff that happens to real explorers like Indiana Jones.
