First you need a base camp tent. Something like this....
You don't park it at the trail head, but find a scenic place with a view.
When you get back to your base camp after a week's hiking, you will enjoy
a porcelain toilet and
a real shower.
If you are lucky, like me, your wife will be waiting for you with a freshly made margarita, beer, or maybe even a refreshing ice cream concoction.
or if you are really, really lucky you will get lobster tail and Champagne.
Now (I am blessed), you get to spend another week with your lovely bride at your secluded campsite, go for day hikes every day, take a shower, have another dinner that can't be beat, and another romantic evening under the stars :)
