An analog week ahead

Isle Royale National Park in Lake Superior can be a scary place...
- Wolves
- Moose
- Leeches
- Unpredictable weather
and perhaps most frightening of all
- No cell phone service
Starting Saturday, 5 outdoor club members and I will be hiking Isle Royale from its northeastern most point to its most southeastern point. The beginning and end points of this 45 mile hike have a few amenities - ranger stations, a lodge, potable drinking water, and stores. But for the majority of the hike across the spine of this large island on the Greenstone Trail, one must to carry what one will need - period.
My pack without water will weigh about 32 pounds. Ultra-light back packers will scoff at such a load. But for those of us who wish to enjoy time in the campsites and sleep snugly and don't need to cover more than a dozen miles in a day and want hot coffee in the mornings, the camp chair and the cushy sleeping pad and the gas stove are worth the few extra pounds.
One thing I will not be carrying will be my cell phone. Instead I will have a digtial camera with an extra battery, a real-live compass/thermometer, a wrist watch, and a paper map of the park.
What I have not yet decided on is whether to bring a print book or my Kindle as leisure reading material. The print book is light and keeps the analog spirit of the trip. But what will I do if I finish the book before the hike is over? What if the battery of my headlamp dies? Can I read the smallish print of a paperback with my cheaters? On the other hand, my Kindle may also run out its battery life. Might it get wet and short out?
The horror of not having something to read is greater by far than that of no Internet by far.
Wish us good weather. And long battery life.
